Newton's Second Law – Part 1
Day 1 of 2
1. We will be accelerating a cart on a track by inclining the track at a small angle.
Initial position
Final position
2. Draw a free-body diagram for the cart. Label your diagram with a set of coordinate
axes (x,y). [Hint: What direction does the cart accelerate? Make that direction the
positive x-direction.]
3. Using your free body diagram, find the net force on the cart?
4. Write Newton's 2nd law for the cart. Plug in the net force from #3.
5. Solve the equation in #4 for the acceleration of the cart. You then have a hypothesis
(prediction) for the acceleration. [HINT: There are some measurements you need to
make in order to calculate the acceleration.]
