Forces and Motion Test Review

Front

Newton's third law states that

Back

For every action, there is an equal and opposite reaction.

Front

Newton's second law states that

Back

Force equals mass times acceleration

Front

Newton's first law states that

Back

An object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed.

Front

The image below shows two opposite forces acting during Tug-a-war, what can we say is true about the effect of the forces on the cart?

Back

The forces are unbalanced, and net force on the rope moves it to the left.

Front

Where is the gravitational pull on earth the strongest?

• closest to earth's core
• on top of a mountain
• on a beach
• at the north pole

Back

closest to earth's core

Front

Why don't we feel a gravitational force between ourselves and other people?

Back

Our gravitational forces as people are so small compared to the earth's gravitational pull.

Front

Example of Newton's First Law of Motion:

• A pencil being thrown across the classroom.
• A volleyball thrown in the air falls to the ground.
• A baseball remains motionless until it is thrown by a player.
• A hockey player pushes off from a wall and moves backwards.

Back

A baseball remains motionless until it is thrown by a player.

Front

When you paddle a boat, as you row the paddle backwards the boat moves forward. Which law is this an example of?

Back

For every action, there is an equal and opposite reaction.

Front

The amount of gravitational force exerted on each other between two objects depends on their:
- Mass and diameter
- Mass and distance
- Distance and volume
- Distance and location

Back

Mass and distance
