Aim: To investigate the factors that affect the height at which a ball bounces.

Background Information:

Energy can neither be created or destroyed. It can only be converted from one form to others. The total amount of energy in any isolated system remains constant.

Types of Energy

* Kinetic

Kinetic energy is the energy a body has by virtue of its motion. The amount of Kinetic energy an object has can be calculated using the following equation:

Kinetic Energy = 1/2 x Mass x Velocity

KE = 1/2 m v

J = 1/2 x Kg m/s

* Thermal

Thermal (or Heat) energy is also measured in Jules. It is energy that an object possesses because it is hot. Thermal energy will conduct or convect from a hot object or area, into a colder object or area. This causes heat to dissipate.

* Gravitational Potential

Potential energy is stored energy that depends upon the relative position of various parts of a system. The work that gravity can do to an object (if it should fall) is called gravitational potential energy. The equation to work out
