Question

What form of energy is possessed by the following:a) Water flowing in a river b) A compressed spring c) A ball rolling on the smooth floor d)An aeroplane in flight e) A metro train passing through an under ground tunnel

Answer 1

• kinetic energy
• Stored, but not used. This energy can become useful when water starts to flow. It will be transferred to kinetic energy and this will cause movement. so it is clear that flowing water have kinetic energy .
• compressed spring=potential energy
• kinetic energy
• As it falls the potential energy is transferred into kinetic energy. When the ball hits the floor the ball is squeezed transferring the kinetic energy back into potential energy, like in a spring.
• kinetic energy. A flying aeroplane has potential energy has it flies above the ground level. And since the aeroplane is flying motion is associated with it and thus possesses kinetic energy. Hence a flying aeroplane has both potential and kinetic energy.
