EOG Prep: Force and Motion 5th Grade NC.5.P.1

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an example of balanced forces?

Back

A car moving at a constant speed.

Front

What is friction?

Back

Friction is a contact force that opposes the motion of an object.

Front

What is an example of a contact force?

Back

Friction is an example of a contact force.

Front

What happens in a tug-of-war when forces are balanced?

Back

Neither side can pull the flag to their side; the forces are equal.

Front

How does mass affect motion?

Back

The greater the mass of an object, the greater the force needed to move it.

Front

What is an unbalanced force?

Back

An unbalanced force causes an object to change its motion.

Front

What is an example of unbalanced forces?

Back

A car speeding up is an example of unbalanced forces.

Front

What does a speed graph show?

Back

A speed graph shows how fast an object is moving over time.

Front

What happens to an object's motion when it experiences friction?

Back

Friction slows down the motion of the object.
