Unit 2 Chapter 1 Review

What forces are causing the swing to move in Figure 1?

• A swing moves up when the force of gravity pushed the person up and the force of gravity pulls the swing down.

• A swing moves down no force is applied.

• A swing moves up when a person pushes up with their legs and pulls down with their legs.

• The swing moves up when the forces are the same.

Which of the following claims about forces and motion is true?

• An object moving in one direction can never begin moving in another direction.

• 1. Some forces, such as pushes and pulls, can cause objects to move.

• 1. An object in motion will always move in one direction and cannot change directions.

• 1. An object that remains in its same position is in motion. 

   

Which claim is correct in describing motion?

• the object has to be not moving to have motion.

• the object has to be moving to have motion and it doesn't matter how fast it is moving.

• the object has to be moving very fast to have motion.

• the object is in motion when it is both moving and not moving.

How do we know that there were forces acting on this tire?

 In Chapter 1, we learned about a floating train in the city of Faraday. What is causing the train to rise?

• The train rises because a force from another object acts on it. I know this because the train moves.

• The train rises because of gravity. I know this because gravity if a forces that pushes up.

• The train rises because of a pulling force. I know this because the train is being pulled up.
