5.P.1.1/5.P.1.4 Study Guide

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 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 is friction?

Back

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

Front

What happens to an object when friction increases?

Back

The object slows down or stops moving.

Front

What is gravity?

Back

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

Front

What is the relationship between force and motion?

Back

Force is needed to start, stop, or change the direction of an object's motion.

Front

If two objects have the same speed, which one is harder to stop?

Back

The object with greater mass.

Front

What is the effect of rolling a ball on a surface?

Back

The ball will roll until friction or another force stops it.

Front

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

Back

Gravity pulls the wagon down the hill, causing it to accelerate.
