Vincent wants to move an object using touching forces. Which test will show that touching forces move objects?  

• He could pull a toy with a string until it hits another toy car

• He could rub a balloon on his shirt and hold it over his head to make his hair stand up

• He could use a magnet to pull a stack of paper clips frmo one end of the table to another without touching the magnet

• He could drop a bouncy ball from very high up

During Experiment 1, a student pushes car X much closer to the center of the seesaw.
Which statements best predict what will happen to the forces and motion as soon as car X starts to move?
Select the two correct answers.

• 
  The seesaw will begin to tilt.

• The seesaw will stop moving and be flat.

• The forces on the seesaw will become balanced.

• The forces on the seesaw will become unbalanced.

• The seesaw will move up and down in a repeated pattern.

Which statement best predicts how the ruler will move after a few minutes have passed?

• The ruler will stop moving, with car X's side of the ruler tilted downward.

• The ruler will tilt up and down faster than when first pushed.

• The ruler will move more slowly and stay more flat than when first pushed.

• The ruler will not be moving, and Car W's side of the ruler wil be sitting on the triangular block

In Experiment 3, the students remove the rubber bands that hold the cars in place on the ruler. They then put a wood block on car W. They use a rubber band to keep the block in place on the car. During the experiment, the students move the cars on the ruler until the ruler is flat.

Which statement best predicts how one of the cars will move at the beginning of Experiment 3?

• Car X will roll across the Ruler toward Car W

• Car W will roll to the center of the ruler and stop.

• Car W will roll across the ruler and crash into Car X

• Car X will roll away from Car W

How can the students move a car to cause the forces to become balanced?

• Push Car X toward the center of the ruler

• Push car W and Car X equal distances toward the center of the ruler

• Push Car W toward the Center of the ruler

• Push Car W toward the edge of the ruler, and push Car X toward the center of the ruler

Dora plans an investigation using one magnet to pick up a pile of metal paper clips. She already knows that the paper clips will stick to the magnet because the two objects attract. Which question can Dora answer by carrying out her investigation?   

• What materials are used to make a magnet?

• Why do paper clips bend easily if they are made frmo metal?

• At what distance will the magnets be abel to pick up the paper clips?

• What touching forces are making the paper clips stick to the magnet?
