Force and Motion: Friction & Gravity Review

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

What happens to a toy car on a smooth surface compared to a rough surface?

Back

A toy car will travel further on a smooth surface because there is less friction.

Front

Why do objects fall to the ground when dropped?

Back

Objects fall to the ground due to the force of gravity acting on them.

Front

What is the effect of oil on friction?

Back

Pouring oil on a surface reduces friction, making it easier for objects to slide.

Front

How does gravity affect satellites in orbit?

Back

Gravity pulls satellites toward Earth, keeping them in orbit.

Front

What is the relationship between mass and gravity?

Back

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

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is an example of a force?

Back

Pushing a door open is an example of a force.

Front

How does friction affect motion?

Back

Friction slows down the motion of objects by opposing their movement.
