Physics 6 & 5 Vocabulary

What is Kinetic Energy?

• A force acting on an object creates a displacement

• A change of momentum

• The rate at which work is done

• The energy from height (and weight)

• The energy from mass in motion

What is Work Energy?

• A force acting on an object creates a displacement

• A change of momentum

• The rate at which work is done

• The energy from height (and weight)

• The energy from mass in motion

What is an Impulse?

• A force acting on an object creates a displacement

• A change of momentum

• The rate at which work is done

• The energy from height (and weight)

• The energy from mass in motion

What is Power?

• A force acting on an object creates a displacement

• A change of momentum

• The rate at which work is done

• The energy from height (and weight)

• The energy from mass in motion

What is Potential Energy?

• A force acting on an object creates a displacement

• A change of momentum

• The rate at which work is done

• The energy from height (and weight)

• The energy from mass in motion

How can a small impulse force produce a large change in momentum?

• When there is less time that the force is applied

• When there is more time for the force to be applied

• When the mass is reduced during a collision

• When the velocity is reduced during a collision
