Question

1. what can happen when objects collide?

a. they speed up.
b. they slow down.
c. they change directions.
d. all of the above

1. what causes the changes when objects collide?

a. energy transfer
b. bowling balls
c. tennis balls
d. bouncing

1. which properties of the objects affect what happens?

a. speed and size
b. speed and weight
c. weight and color
d. weight and temperatur

1. if a bowling ball and tennis ball collide, what happens? why?

Explanation:

1. The text states collisions can slow objects, change their direction, and energy transfer can also result in speed changes in some interactions, so all options apply.
2. The opening paragraph explains collision changes come from energy transfer as energy is transformed between objects or to the environment.
3. The text explicitly says the speed and weight of objects affect collision outcomes.
4. The reading describes this specific collision and the reason tied to the objects' relative weights.

Answer:

1. d. all of the above
2. a. energy transfer
3. b. speed and weight
4. The bowling ball will make the tennis ball change directions. This is because the bowling ball weighs more than the tennis ball.
