5th Grade Force and Motion NC

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is speed?

Back

The distance an object travels per unit of time, often measured in meters per second (m/s).

Front

What is average speed?

Back

The total distance traveled divided by the total time taken.

Front

What is friction?

Back

A force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms (kg).

Front

How does mass affect motion?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What happens to the speed of an object thrown upwards?

Back

It slows down until it stops at the highest point before coming back down.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its speed or direction of motion.
