Last week in class you performed a lab activity:

1. Record the time at 0.5 meter intervals of a cart with a 2 kg weight being pulled with constant force. Repeat 3 times.

2. Add an additional 2 kg weight to the cart, Perform 3 more trials

3. Continue adding weights and performing three trials until you are done or out of time.

With the data you collected, I created the graph to the right. Using the graph as evidence answer the following question in the form of a CER.

When the cart is pulled with a constant force how does changing the mass of the cart affect the acceleration of the cart?
