1) On a Velocity-time Graph, the axis tells you the velocity. Calculating the slope gives you the of the object. Circle the Correct Answer 2) On a Position-time Graph, constant velocity is a straight line or a curve. Changing velocity is a straight line or a curve. 3) On a Velocity-time Graph, constant velocity is a straight horizontal line or a straight diagonal line. Changing velocity is a straight horizontal line or a straight diagonal line. 4) Positive velocity means toward or away from the origin. Negative velocity means toward or away from the origin. 5) When the ramp angle increased, the slope (acceleration) on the Velocity-time graph increased or decreased. 6) On a Velocity-time graph, the acceleration is always positive or negative when the motion sensor is at the bottom of the ramp. Short Answer 7) What is the possible range (smallest to largest) of accelerations that your cart can have? Hint: To answer this question, consider the possible range of angles you could put your ramp could have, from 0 (perfectly horizontal) to 90 (throwing something straight up into the air and letting it free fall back down)
