Front

What are the factors that affect friction?

Back

The type of surfaces in contact and the amount of force pressing them together.

Front

Which surface creates more friction: grass, sidewalk, sand, or ice?

Back

Back

Friction between the bike's brakes and the wheels causes it to slow down.

Front

Why can astronauts jump higher on the moon?

Back

Astronauts can jump higher on the moon because the moon has weaker gravity than 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 the effect of gravity on falling objects?

Back

All objects fall at the same rate due to gravity, regardless of their mass.
