Part A: Students study how the temperature of a substance is related to the rate of molecular movement. Name a substance where molecules are moving the fastest?

• Water

• Sugar

• Liquid

• Oxygen

Part B: Describe the relationship between temperature and kinetic energy of gas particles.

• There are no particles

• As the particles speed up, kinetic energy decreases

• As particles speed up, kinetic energy increases

• As particles speed up, potential energy increases

Newtons Third Law states

• That for every action there is an equal and opposite reaction

• An object at rest will remain at rest

• Motion is caused by force

• That for every action there is an unequal reaction

What happens when two objects collide?

• Energy is transferred

• The objects resist each other

• If the force is the same (balanced force), there will be no movement. If the force is unequal (unbalanced) there will be movement

• Nothing happens
