5.6/5.7 Science Study Guide

Front

What is a force?

Back

A force is a push or pull on an object that can make it change speed, direction, or location.

Front

What does gravity do?

Back

Gravity is a force that tries to pull objects towards each other.

Front

Which has the least gravitational effect on Earth: objects on Earth, birds, light from the stars, or water flowing through a river?

Back

Light from the stars has the least gravitational effect.

Front

Can you jump higher on the moon or the Earth? Why?

Back

You can jump higher on the moon because it has less gravity.

Front

Will gravity pull a person down or out to space? Why?

Back

Gravity will pull a person down towards the Earth.

Front

What is the relationship between mass and gravity?

Back

The more mass an object has, the stronger its gravitational pull.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion, making it harder for objects to move.

Front

What happens to an object's motion when a net force is applied?

Back

When a net force is applied, the object's motion will change in speed or direction.

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.
