Force and Motion 4

Joaquin has hockey practice at the same ice rink where Alton has curling practice. One day, they were both playing on the ice with their equipment. They noticed two crashes in particular:

In Crash 1, Alton’s curling stone with more mass was moving along and crashed into Joaquin's hockey puck.

In Crash 2, Alton's curling stone with less mass was moving along and crashed into Joaquin's hockey puck.

It was the same hockey puck with the same mass in both crashes. And also in the crashes, both curling stones slowed down by 4 m/s.

In what ways might the pucks' motion have been changed by the crashes?

• It might have changed direction.

• It might have stopped moving.

• It might have started moving.

• It might have slowed down.

• It might have sped up.

What about the crashes would have caused the pucks' motion to change?

• The friction between the ice and the puck

• The force of the curling stone on the puck

• The change in velocity of the puck.

• The mass of the puck.

It was the same hockey puck with the same mass in both crashes. And also in the crashes, both curling stones slowed down by 4 m/s.

In which crash did the curling stone experience greater force? How do you know?

• Crash 1 with the more massive stone. Because if two objects slow down by the same amount, the less massive one takes more force to slow it down.

• Crash 1 with the more massive stone. Because if two objects slow down by the same amount, the more massive one takes more force to slow it down.

• Crash 2 with the less massive stone. Because if two objects slow down by the same amount, the less massive one takes more force to slow it down.

• Crash 2 with the less massive stone. Because if two objects slow down by the same amount, the more massive one takes more force to slow it down.

In which crash did the hockey puck experience greater force? How do you know?

• Crash 1 with the more massive stone. Because the hockey puck experiences a greater force than the stone because it is less massive.

• Crash 1 with the more massive stone. Because the hockey puck experiences the same force as the stone; and the stone in Crash 2 experienced a greater force than the stone in Crash 1.

• Crash 1 with the more massive stone. Because the hockey puck experiences the same force as the stone; and the stone in Crash 1 experienced a greater force than the stone in Crash 2.

• Crash 2 with the less massive stone. Because the hockey puck experiences the same force as the stone; and the stone in Crash 2 experienced a greater force than the stone in Crash 1.
