If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Since the velocity is constant, the acceleration and the net force are 0 m/s/s and 0 N respectively. The velocity of an object is equal to the displacement made by the object per unit of time. It bounces three times (vertically), each time rising up not as far as the time before. After the students have completed the guided practice problems with me, I tell them that they will work with their table groups to complete Worksheet #3 Constant Velocity Calculations.I make sure to emphasize that they will be graded on showing their work by putting the equation that they chose to use in symbols, calculating the correct answer, and applying the correct units to their answer. If you're seeing this message, it means we're having trouble loading external resources on our website. So, v 0 v_0 v 0 is the initial velocity, and x 0 x_0 x 0 is the initial position.
