Energy is defined as

• the ability to do work

• anything that has volume and mass

• a group of interacting elements forming a complex whole

• a measure of how much matter is present in a substnace

The graph shows that if the mass of an object doubled (2x)

• the kinetic energy stays the same

• the kinetic energy is reduced to half (1/2x)

• the kinetic energy also doubles (2x)

• the kinetic energy quadruples (4x)
