Front

What force decreases when soap becomes wet?

Back

Friction decreases as the soap becomes wet.

Front

Why can Magnet 1 hold up a drawing while Magnet 2 cannot hold up a calendar?

Back

The calendar has a greater mass than the drawing.

Front

What can be done to make an action figure fall to the ground more slowly when using a parachute?

Back

Add weights to the action figure.

Front

Why did Miguel use more force to push Box 2 than Box 1?

Back

Box 2 was heavier than Box 1.

Front

What force must a rocket act against as it moves away from Earth?

Back

Gravity.

Front

Define friction in the context of motion.

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with the mass of the object.

Front

How does the mass of an object affect the force required to move it?

Back

A heavier object requires more force to move than a lighter object.

Front

What is the role of air resistance in the motion of falling objects?

Back

Air resistance opposes the motion of falling objects, slowing their descent.

Front

Explain how adding weight to an object affects its fall when using a parachute.

Back

Adding weight increases the downward force, which can lead to a faster fall if the parachute does not provide enough lift.
