Energy - JSS2 Basic science Past Questions and Answers - page 2

An example of potential energy is a stretched rubber band. When you stretch a rubber band, it stores potential energy due to its stretched position.

Kinetic energy is directly related to the speed of an object. The faster an object moves, the more kinetic energy it has.

The amount of work done when moving an object depends on the force applied and the distance over which the force is applied. So, factors such as the magnitude of force and the distance traveled influence the work done.

Work done can change an object's energy by transferring energy to or from the object. For example, if you push a box and it moves, you're doing work on it, transferring energy to increase its kinetic energy.

The potential energy of an object changes with its position. For example, as an object is lifted higher against gravity, its potential energy increases because it's being raised to a higher position.

n object would have both potential and kinetic energy simultaneously when it  is in motion while also being at a position where it can potentially do work. For example, a swinging pendulum has both kinetic energy due to its motion and potential energy due to its position at the top of the swing.
