Unit 2 Force and Motion Review

A toddler throws a block at a wall and neither break. How do the block and the wall act on each other?

• The block exerts a stronger force than the wall but in the same direction.

• The block/wall exert forces that are equal in magnitude and in direction

• The block/wall have forces that are equal in magnitude but opposite ways

• The block exerts a stronger force than the wall but in the opposite direction.

Which ball should a bowler use so that his acceleration increases and gets a strike?

• Bowler should choose a ball with more mass or throw the ball w/more force.

• Bowler should choose a ball with less mass or throw the ball w/more force.

• Bowler should choose a ball with more mass or throw the ball w/less force.

• Bowler should choose a ball with more mass or throw the ball w/less force.

What would cause the momentum of a moving object to increase?

• Force acting in the direction opposite the object’s motion is removed

• Two forces of equal magnitude act on the object in opposite directions.

• Force acting in the direction of the object’s motion is removed

• A new force acts on the object, opposing the object’s motion.
