Question 2
2.
Which puck(s) experienced the strongest force when hit? How do you know?
All three hockey pucks experienced the same force because they changed speed by the same amount.
The
second
hockey puck; it is more massive and has the fastest ending speed.
The
third
hockey puck; it takes a stronger force to slow down a more massive object than to speed it up.
The
second
and
third
hockey pucks; they have more mass than the green puck, but changed speed by the same amount.
Keys for Success:
- Force = Mass x acceleration
- F=MA
Written response CFS: (3 pts each)
CFS:
accurately identifies the changes to each object in a collision
accurately describes the relationship between force, mass and velocity in a collision
