Force and Motion Unit Test

A mother and daughter press their hands together and then push apart while ice skating. Immediately after they push away from each other, how does the motion of the mother and daughter change?

• The mother moves forward, and the daughter moves backward with a greater acceleration.

• Both move forward, but the mother moves with a greater acceleration.

• The mother moves backward, and the daughter moves forward with a greater acceleration.

• Both move backward, but the daughter moves with a greater acceleration.

A pitcher throws a ball toward a player holding a bat. The player uses the bat to hit the ball. What statement correctly describes the reaction force between the bat and ball?

• The reaction force is the force that causes the ball to move toward the bat.

• The reaction force is the force applied to the bat by the player holding the bat.

• The reaction force is the force that pulls the ball toward the ground.

• The reaction force is the force of the ball on the bat.

Which student is correct?

• Student 1 because opposing forces are absent

• Student 2 because the forces act in the same direction

• Both students because either the forces are identical or the masses are identical

• Neither student because either the forces are different from each other or the masses are different from each other
