Q & A: Which ball falls fastest. Learn more physics! Great question. As it turns out, the force of gravity tries to make everything accelerate downward at EXACTLY the same rate, no matter how light or heavy it is. This means that if you dropped a basketball and a tennis ball at the same time (from the same height) they will hit the ground at ...

Ari had one ball and two ramps. The ramps were identical except that one had a sandpaper surface and one had a plastic surface. Ari measured how long it took the ball to roll down each ramp. Ari most likely was investigating the effect of which force on the speed of the ball?

The reduction of effective gravity by the Earth's rotation. One important rotating frame is the surface of the Earth, rotating with a period of about 24 hours--more accurately, 23 hrs 56.07 min or 86164 seconds. If the equatorial radius of Earth is 6378 kilometers, the circumference comes to 40074 kilometers--slightly more than the 40,000 ...

Obviously it does but it depends, the more friction the surface produces the slower the ball will go. Also it depends on how you are going to roll the ball, using a ramp or by hands.

On What surface did the ball roll faster? _____ 1 See answer dokyungsoo30 dokyungsoo30 Answer: You should find that a solid object will always roll down the ramp faster than a hollow object of the same shape (sphere or cylinder)—regardless of their exact mass or diameter. I hope that helped. #CaringOnLearning ...

In the real world things roll to a stop because of friction, air resistance, and deformation, so in this context "realistically" means: The ball slows gradually relative to the rolling resistance coefficient or friction coefficient of the surface. A higher value should slow the ball faster. The ball does not stop if the angle of the surface is ...

2. Divide this number into 40.91 (i.e. 40.91/2.52 = 16.23 mph). Ball Track - The portion of the bowling ball, which comes in contact with the lane as it rolls down the lane. Bifilar - The use of two cords or wires to support the test cradle in testing the radius of gyration of a bowling pin.

The ball will roll the furthest on the concrete because the concrete is a smooth surface meaning that the ball will smoothly roll along it. The ball on the grass in going to go to have a smaller distance than the ball on concrete because the grass if rough and un-stable meaning that the ball has less chance of rolling a long distance

The same principles apply to spheres as well—a solid sphere, such as a marble, should roll faster than a hollow sphere, such as an air-filled ball, regardless of their respective diameters.

How does the type of surface a ball rolls over affect the rate at which it rolls? By: Hiba Sirguroh Results First Test In conclusion, as stated in the hyposthesis, the ball rolled fastest over the timber surface. Method Discussion The reason the ball rolled the fasted over the

This ball hooks noticeably earlier than the one at 4,000 and will not hold the pocket. After making an adjustment of five boards with the bowler's feet, the 1,000-grit ball now will hold the line to the pocket. Surface is the biggest influence on your ball's reaction. Surface dictates about 70 percent of the total ball motion.

(a-c) The type of motion depends on where the cue hits the ball. (a) If the cue hits the ball at exactly (frac{7}{5} R) above the table, the ball will exhibit pure rolling motion, (omega = vR). (b) If the cue hits the ball above the critical spot, it will rotate faster than translate (omega gt vR) and exhibit a slipping rotation.

$begingroup$ In regard to Chris2807's answer, I have a question: If a ball is rolling down the hill on its own, there is a continual component of gravitational force that pulls it down the incline. Since this force produces no torque about the center of mass, I have concluded that a frictional force must be exerted on the contact point at all times when the ball slides down the incline, or ...

Answer (1 of 2): The fibres in the carpet and the blades of grass (and other particles such as clumps of dirt) may provide resistance, which would likely slow the ball down.There's also the factor that, unless we're talking about artificial grass, it's also likely that the surface of the grass will be nowhere as even as a tiled surface, which means slopes and inclines could affect the speed of ...

Bill Hall. Be sure that ball speed is really what you need. The surface of the ball, the volume of oil on the lane, and the lane surface all can affect ball speed. The first thing you need to do is to make sure that you have a rhythm that can help you generate the speed you want. A common mistake is that bowlers will put the ball into the swing ...

20%On what surface does a ball roll faster on. ... I would like to know different types of surfaces that would make any kind of ball roll faster. Also what would be the different variables of the ball rolling faster in the sequences. Submitted: …

Anonymous said... your movie is good, but the background is not appropriate with the font color, but you did a good job and I wish for you the best. Although some students think that your experiment is simple, but it's too interesting to me because it …

Lane Dederer. There are multiple factors affecting the velocity a ball gains while descending an inclined plane. One simple factor that will affect the velocity of a ball rolling down an incline is the angle of the incline. This is due to the fact that when the angle of the incline is …

Read the book Balls. It is a quick and simple book that shows kinds of balls and how they can move. Next place your students in small groups. Give each group a different ball. The task for the group is to think of five words that describe or tell about the ball. Words can include description of size, color, texture, type of material and use.

The reason a ball rolls farther on dirt is because the grass has more potenial than dirt because once you roll the ball really hard the ball will slow down on grass and the grass is sometimes standing up and the dirt doesn't have any thing to stop the ball the dirt is is flat unlike the grass.

roll of a certified soccer ball is effected by the surface texture and the weather. The purpose of the experiment is to understand the mechanisms and principles of friction, acceleration, air and wind resistance, force, and other types of friction or forces. This will further help find the best playing field's weather and what texture ...

It would depend. The ball will roll faster on the path of least resistance. If the grass is cut very short and surface is even and dry, there could be less resistance than if the dirt were most and not compact or even/flat. Again, it depends on the condition of the surface and which one …

Does A Ball Roll Faster On A Smooth Surface Or On A Rough Surfaces? Physics. Assuming the smooth surface is flat and level, based upon equations involving rates and time a smooth... A Ping Pong Ball With A Mass Of 2.20 Grams Rolls Along A Frictionless Table With A Velocity Of 0.850 M/s.

This type of friction is called rolling friction. Rolling friction is affected by the texture of both the surface and the rolling object. Had I used a tennis ball it probably would have rolled a shorter distance because of the ball's texture. Rolling friction is also affected by how large the …

$begingroup$ Air drag depends on the surface area and the velocity$^2$. The larger ball will experience slower acceleration and will be behind when the small ball reaches terminal velocity. It would need to be a very long slope for the larger ball to catch up and pass the smaller ball. $endgroup$ –

What does Neosporin do inside my wound that makes it heal so much faster as well as how does the treating of a wound a certain way prevent scar tissue from forming? I don't know much about the body's healing process but as someone who gets hurt a lot I am realizing I may need that 5 year old explanation my mother never gave me.

This also explains why different skateboard wheels will be faster or slower on different surfaces. A hard wheel will go real fast on nice smooth surfaces. A softer wheel will "grip" to the surface more and slow you down (you can notice the difference if you try to drag a hard wheel and a soft wheel across a smooth floor).

Because the surface of the sidewalk is smoother than the surface of the grass and therefore there is less friction on the sidewalk which makes it easier for the ball to roll, and because its ...

The steeper the ramp the faster it speeds up. (If this doesn't make sense, imagine a ball rolling down a board. If the board is almost straight up and down, then the ball is basically falling, so it's speeding up really quickly. But if the board is almost flat with the ground, it will take a lot longer for the ball to roll down it.)

When you roll a ball on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops because of friction. Keep questioning! Answer 2:

A car's speed is often determined by the friction between its wheels and the road. When you drove your toy car over the smooth tile, the wheels were met with little resistance. Try sweeping your finger against the tile --is it met with any resistance, anything that somehow stops it from moving ...

The ball rolls because: the friction present between the surface pushes the atoms/particles in contact with surface or ground backwards, hence with centre of mass moving in a direction, the ball's bottom surface (ie. The surface in contact) moves in opposite direction or backwards, causing the ball to roll. The ball slips because there is no ...

How to Match the Roller Cover to the Surface Choosing the correct roller cover starts with knowing the sheen of paint you will be using. Once you've picked either a woven or knit roller, the next characteristic you want to focus on is the nap height, which is the length of the fibers that extend from the backing and carry the paint to the wall.
