Answer :
- Kinetic energy is the energy of motion
- The potential energy of an object depends on its mass and its height
- The law of conservation of energy states that energy can be neither created nor destroyed, but it can change its form
- Stored energy is called potential energy
- When you move your hand or foot, your body has converted potential energy into kinetic energy
- When coasting while roller skating, you eventually stop due to friction
What is energy?
Energy refers to the ability or capacity to do work. Energy can be of various types as follows:
- Mechanical energy (kinetic or potential)
- Electrical energy
- Light energy
- Solar energy
- Heat energy
Kinetic energy is energy possessed by an object because of its motion while potential energy is energy possessed by an object because of its position or its condition.
The law of conservation of energy states that energy cannot be created nor destroyed but can only be transformed i.e. converted from one form to another.
Friction is a force that resists the relative motion or tendency to such motion of two bodies in contact.
