Activity 6: Newton's Second Law

Question 1

What did we do in Activity 6?

Answer 1

In the first activity, a motion sensor was placed on a level precision track. A cart and a metal bar are rolled down the track, and a velocity versus time graph was created using DataStudio.

The second activity required the precision track be placed on an incline. The angle of incline was adjusted to ensure the cart experienced an acceleration of zero (constant speed).

Question 2

What is the equation to determine f?

Answer 2

f=mgsinθ

Question 3

Equation to determine F

Answer 3

∆F=f√([(∆m/〈m〉 )²+(∆a/〈a〉 )²] )
