Eileen studies the types of forces on a steel ball. She begins by drawing a force diagram

for the ball when it is not moving. Her drawing is given.

Then she pushes the ball to the right and draws the following force diagram for the ball.

A student claims that invisible fields exist between objects that are not in contact.

Which TWO arguments BEST support her claim

•  A ball rolls more slowly on a bumpy road than on a smooth road.

• A magnet attracts a paper clip causing it to move toward the magnet.

• Two positively charged balloons repel each other when they are brought

  close together.

Two charged balloons repel each other. What electrical charges might the balloons

have?

• negative and neutral

• positive and neutral

• positive and positive

A student is investigating with magnets. She places one end of a bar magnet near the end of another bar magnet. The diagram shows her investigation.

The student claims that the two magnets have a magnetic field that exist between them. The will happen that will support the student's claim?

• The magnets will repel each other as the closest poles have like charges.

• The magnets will repel each other as the closest poles have opposite

  charges.

An object (such as a ball) tossed in the earth's atmosphere slows down because of air resistance (which is a force).

 

Based off the information provided above, please respond to the question below using the RACE (Restate the question, Answer the question, Cite evidence from text, and Explain further/make connections) strategy:

 

 

Do you think an object can be moved without using force? Why or why not?
