Lab: Acceleration of a Cart on a Track PART I Make predictions about the position, velocity, and acceleration of a cart in different scenarios.

If the air track is perfectly level, what do you think will happen to the velocity of the cart as it slides along the track? Will it increase, decrease, or stay the same? Justify your answer.

If the air track is slightly tilted, what do you think will happen to the velocity of the cart as it slides down the track? Justify your answer.

If the mass of the cart is increased, how will the velocity at the bottom of the track for this more massive cart compare to the velocity at the bottom of the track for the lighter cart in the previous prediction? Justify your answer.

If the mass of the cart is restored to its original value, but the incline is increased, how will the velocity of the cart at the bottom of this more inclined track compare to the velocity of the cart at the bottom of the track for the lesser incline? Justify your answer.
