5th Grade Force and Motion NC

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. On Earth, it pulls objects toward the center of the planet.

Front

What is speed?

Back

Speed is the distance an object travels in a certain amount of time. It is calculated by dividing distance by time.

Front

What happens to the speed of a ball thrown straight up?

Back

The ball goes slower and slower as it rises, stops at the top, and then speeds up as it falls back down.

Front

What causes a bicycle to slow down when brakes are applied?

Back

The brakes create frictional forces on the wheels of the bicycle, which slows it down.

Front

What is the role of gravity when a wagon goes down a hill?

Back

Gravity pulls the wagon down the hill, causing it to speed up.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is a force?

Back

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

Front

How does friction affect motion?

Back

Friction can slow down or stop the motion of an object by opposing its movement.

Front

What is the formula for calculating speed?

Back

Speed = Distance ÷ Time.
