What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air. It slows down falling objects.

Front

What happens to gravity when two objects are far apart?

Back

The force of gravity between two objects decreases when they are far apart.

Front

What happens to gravity when two objects are close together?

Back

The force of gravity between two objects increases when they are close together.

Front

What must a rocket overcome to leave Earth's surface?

Back

A rocket must overcome gravity to leave Earth's surface.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger the gravitational pull it has.

Front

What is weight?

Back

Weight is the force of gravity acting on an object. It depends on the object's mass and the strength of gravity.

How does air resistance help a parachute?

Back

Air resistance slows down the fall of a parachute, allowing a person to land safely.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes all objects to fall towards the Earth at the same rate, regardless of their mass.
