What does F=MA tell me in need to identify to find force?

Why should I not use the final velocity of 15m/s to determin force? (think: what is acceleation?)

Which golf ball(s) experienced the strongest force when hit? How do you know?

Three golf balls with the same mass were rolling on the ground.

Which puck(s) experienced the strongest force when hit? How do you know?

How can you use the F=MA equation to identify the puck the experiences the strongest force?

Your wheelchair has 3 different trials to see how fast it can go with different amounts of force applied. The table below shows the results from the 3 different trails.

What evidence can you find that one of the chairs receives more force than the others?

CFS:

• accurately identify the change in the dependent variable (velocity)

• accurately describes the relationship between force, mass and velocity
