4th Grade Forces

Front

What is gravitational force?

Back

Gravitational force is the force that pulls objects toward each other. The more mass an object has, the stronger its gravitational pull.

Front

What tool is used to measure weight?

Back

A spring scale is used to measure weight by the amount of force exerted by gravity on an object.

Front

What happens when like poles of magnets are brought together?

Back

Like poles of magnets repel each other, meaning they push away from each other.

Front

Which surface has the least amount of friction?

Back

An ice skating rink has the least amount of friction, allowing skaters to glide smoothly.

Front

What force causes a rolling ball to eventually stop?

Back

Friction is the force that slows down and stops a rolling ball.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in grams or kilograms.

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 that can change the motion of an object.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth, causing them to fall.
