What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, slowing it down.

Front

How does a parachute work?

Back

A parachute uses air resistance to slow down a person's fall to the ground.

Front

What happens when you drop a hammer and a feather?

Back

The feather falls slower than the hammer because air resistance affects it more.

Front

What force must a rocket overcome to leave Earth?

Back

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

Front

What is inertia?

Back

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

Front

What is the relationship between mass and gravity?

Back

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

Front

What is weight?

Back

Weight is the force of gravity acting on an object, depending on its mass and the gravitational pull of the planet.

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, unless air resistance is significant.
