Kinetic Energy
2

• Kinetic Energy is energy of motion

3

• The particles in substances gain kinetic energy
  as they warm, and lose kinetic energy as they cool

4

• Matter expands when the kinetic energy of its
  particles increases matter contracts when the
  kinetic energy of its particles decreases

5

• Particles of substances are always in motion
• The amount of motion can change

6

• Objects in motion have energy.
• Energy of motion is called kinetic energy
• There is a direct relationship between the amount
  of motion and the amount of kinetic energy

7

• The kinetic energy of particles is heat
• As the amount of kinetic energy increases, heat
  increases
• And vice-versa..

8

• The amount of heat (particle kinetic energy) can
  change as a result of energy transfer
• Energy transfer occurs when particles come in
  contact with one another
