4. RERUN: Results Use your two data tables to analyze your results.
Guiding questions:
How does changing the force affect the motion of the cart?
The greater the constant force pushing on an object, the…
How does changing the mass affect the motion of the cart?

5. Wrap-up questions: Answer in notebook
What is Newton’s Second Law of Motion?
If I apply the same amount of force to two different carts, and one has more mass than the other, which will accelerate faster? Use Newton’s Second Law to answer this question.
If I apply a large force to Cart A, and a small force to Cart B, how do their accelerations compare? Assume that both Cart A and Cart B have the same mass.
I am pushing a full shopping cart. If I want to increase the acceleration of my cart, what are two ways I could do this? Use Newton’s Second Law to answer this.

6. Back to Newton’s First Law: Answer in notebook
Use Newton’s first law to explain why it is harder to move the heavy cart and easier to move the light cart.
Which cart is easier to stop, the light cart or heavy cart? Why?

7. RERUN: Uncertainty
