5.P.1.4 #7: Schoolnet

Front

What is force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is mass?

Back

The amount of matter in an object, which affects its inertia and how much force is needed to change its motion.

Front

What is speed?

Back

The distance an object travels per unit of time.

Front

What is momentum?

Back

The product of an object's mass and its velocity, representing how much motion it has.

Front

What happens when a force is applied to an object moving at a constant speed?

Back

The object will change speed.

Front

What are equal and opposite forces?

Back

Forces that are the same in size but opposite in direction, resulting in no change in motion.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and momentum?

Back

Greater mass results in greater momentum if speed is constant.

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Forces that are not equal, causing a change in motion.
