Objective: SWBAT describe and calculate the relationship between force, mass, and acceleration in a collision

Do Now:

Question 1
1.



What is the relationship between the force on each object in a collision?

Question 2
2.

Alice and Kai were playing air hockey, which is a game where players hit a puck with paddles so the puck slides across a table. After the game, they were crashing the puck and two different paddles. The puck was the same in both crashes, but the paddles were different: the red paddle had less mass, while the purple paddle had more mass. Use the information in the diagram to answer.

Question 3
3.

Question 4
4.

Calculate the force of the Red Paddle on the hockey puck.

How much force was applied to the hockey puck by the Red Paddle during the collision?

Question 5
5.

What do you know about the force on the hockey puck compared to the red paddle?
CFS:
  • accurately describes the relationship between force, mass and velocity in a collision

In which crash did the puck experience a stronger force? Why?
The puck , did not, experience a force; only the paddles experienced a force in the crashes.
Crash 2; the force on the purple paddle was stronger in this crash, so the force on the puck was also stronger.
The diagram doesn’t tell you anything about the force on the puck. It only gives information about the force on the paddles.
The puck experienced the same force in both crashes. The paddles changed speed by the same amount in each crash, so the force on the puck was the same each time.
