Force and Motion Vocab

What is momentum?

• Speed of an object at one instant of time.

• The tendency of an object to resist a change in its motion.

• The total distance divided by the time taken.

• A measure of how hard it is to stop an object.

What is mass?

• Formula for momentum

• Formula for speed

• Speed AND direction of a moving object.

• The amount of matter in an object.

What is acceleration?

• Speed of an object at one instant of time.

• The tendency of an object to resist a change in its motion.

• Slowing down.

• Change in velocity divided by the time it takes for the change to occur.

What is inertia?

• Speed AND direction of a moving object.

• The tendency of an object to resist a change in its motion.

• Unit used to measure speed.

• Unit used to measure acceleration.

What is average speed?

• Formula for momentum

• The total distance divided by the time taken.

What is the law of conservation of momentum?

• Formula for acceleration

• Unit used to measure acceleration.

• When objects collide the total initial momentum and final momentum are equal.

• Speed of an object at one instant of time.

What is instantaneous speed?

• The tendency of an object to resist a change in its motion.
