Looking at the picture, which student threw the ball with MORE energy? ​

• The ball bounced back closer to student 1 than student 2.

• The ball bounced back closer to student 2 than student 1.

• The ball hit the wall at a higher point for student 1 than student 2.

• The ball hit the wall at a higher point for student 2 than student 1.

Which of the following would increase the gravitational potential energy of a marble on a ramp?

• make the top of the ramp higher off the ground

• make the ramp flat

Pierce and Levi tested different surfaces and made predictions about what will happen when objects collide. 

They tested the objects on a track like the one seen below.

Which prediction would be most likely for the collision of the large plastic ball and large steel ball?

• The large steel ball will continue rolling straight, but the large plastic ball will roll backward.

• The large plastic ball will continue rolling straight, but the large steel ball will roll backward. 

• The large plastic ball and large steel ball will collide and stop.

• The large plastic ball and the large steel ball will collide, and both will roll backward.

Pierce and Levi tested different surfaces and made predictions about what will happen when objects collide. 

They tested the objects on a track like the one seen below.

Which prediction would be most likely for the collision of the small foam ball and small steel ball?

• The small foam ball and the small steel ball will collide and stop. 

• The small foam ball will roll back in the opposite direction while the steel ball keeps rolling in the same direction. 

• Both will bounce back in the opposite direction. 

• They will knock each other off the track.

Pierce and Levi tested different surfaces and made predictions about what will happen when objects collide. 

They tested the objects on a track like the one seen below.

Which is true about collisions? (Select all that apply)

• The greater the force, the harder the collision. 

• Friction can slow down an object and reduce the impact of a collision.

• If forces are equal, there will not be a collision.

• The mass of an object does not affect the collision.
