Question 1

Two teams are playing tug-of-war. Team A pulls to the left with a force of 50 newtons. Team B pulls to the right with a force of 50 newtons. The rope does not move. Which statement best describes the forces on the rope?

The forces are balanced, so the rope stays in place. The forces are unbalanced, so the rope will speed up. The rope does not move because there are no forces acting on it. The rope will move toward the team that pulls last.

The forces are balanced, so the rope stays in place.

Question 2

An iron nail A plastic spoon A wooden pencil A glass marble

Question 3

On a dry winter day, a student rubs a balloon against her hair. Her hair then stands up and is pulled toward the balloon. What is the most likely cause?

Static electric charge built up on the balloon and attracts her hair. The balloon becomes magnetic and pulls on her hair. Gravity between the balloon and her hair gets stronger. The balloon gets heavier and pushes the hair upward.

Correct Answer:

Static electric charge built up on the balloon and attracts her hair.

Question 4

A student pushes a swing. After the student lets go, the swing moves back and forth, going a little less high each time. Why does the swing eventually come to a stop?

Friction and air resistance transfer the swing's energy to other forms. The swing runs out of force and has to be pushed again. Gravity pulls the swing down only when it is moving. The swing stops because no energy was ever given to it.

Correct Answer:

Friction and air resistance transfer the swing's energy to other forms.

Question 5

A cart rolls along a track and bumps into a stationary block of wood. The block slides forward after the collision. What best explains what happened?

Energy was transferred from the moving cart to the block during the collision. The block created its own energy to start moving. The cart's energy disappeared completely when it hit the block. The block was pulled forward by gravity from the cart.

Correct Answer:

Energy was transferred from the moving cart to the block during the collision.
