The buoyant force is the upward force exerted on an object wholly or partly immersed in a fluid. This upward force is also called Upthrust. Due to the buoyant force, a body submerged partially or fully in a fluid appears to lose its weight, i.e. appears to be lighter. Following factors affect buoyant force: the density of the fluid.

Substances expand (increase in size) when they get warmer, and they contract (decrease in size) when they get cooler. This property can be useful. For example: Thermometers work because the …

Cognitive Science. Cognitive science is the interdisciplinary study of mind and intelligence, embracing philosophy, psychology, artificial intelligence, neuroscience, linguistics, and anthropology. Its intellectual origins are in the mid-1950s when researchers in several fields began to develop theories of mind based on complex representations ...

Pressure is defined to be the amount of force exerted per area. So to create a large amount of pressure, you can either exert a large force or exert a force over a small area (or do both). In other words, you might be safe lying on a bed of nails if the total surface area of …

The cricket ball will hurt more when it hits you, that is, when it comes to rest. Nuclear energy – the energy stored in the nucleus (centre) of an atom. Energy is released when either the nucleus is split apart (called nuclear fission) or when nuclei are combined (nuclear fusion).

Energy is constantly changing forms and transferring between objects, try seeing for yourself how this works. Use two balls to transfer kinetic energy from the the big ball to the smaller one and see what happens. A large, heavy ball such as a basketball or soccer ball. A smaller, light ball such as a tennis ball or inflatable rubber ball.

Ball and socket joints are perhaps the most versatile synovial joints. They are muti-axial joints, which means they can move in many axes. One joint has a ball and the other joint has a socket. The shoulder joint and the hip joints are examples of this type. In the hip joint, the ball is the head of the leg bone (femur) while the socket is the ...
