Question

Prediction Questions: The predictions provided on each lab handout are to help you prepare for the lab session. The questions will typically ask you to either do a calculation or think about a concept that will be used in the lab.

Predictions:  Answer the following prediction questions and turn them in at the beginning of lab.  Each individual is responsible to turn in their own set of predictions (no group predictions please).

1.Predict what the position, velocity and acceleration graphs will look like for a cart rolling UP an inclined ramp.  The cart will roll up (slowing as it goes), stop, and then roll back down with the motion detector placed at the top of the incline.

2.Predict what the position, velocity and acceleration graphs will look like when a cart is rolled along a horizontal track and slows due to friction (the cart is moving toward the detector).

3.Predict what the position, velocity and acceleration graphs will look like when a cart on a horizontal air track has a hanging mass (mass on a hanger connected to the cart with a string over a pulley) which causes the cart to accelerate (the cart moves first toward the detector and then away from the detector).
