possible reasons they are not. 3. Consistent, repeatable measurements constant velocity, is not Pushing the cart with your hand, trying to keep it moving with a and the cart which has a easily repeatable. Set up one end of the ramp with the ramp stop away from the ramp spring-loaded launcher up against it with the cart's launcher facing first cart's stop. Launch the other cart 5 times using the number setting of ion Take data each time of the second cart's and velocity. Determine the slopes of the position versus time graphs and determine the corresponding average velocities of the versus Enter Velocity versus Time Position versus Time Slo 2. 36a t 60 3. 4. o 2007 .00

Systematic

Air resistance

friction variation

3) Average velocity is measured as total displacement/time

Instantaneous velocity is velocity at any particular instant of time

For eg

While covering a distance via car, the speedometer gives the magnitude of instantaneous velocity which ranges from zero to the maximum speed at which you can drive

Whereas average velocity will be total displacement/ total time taken for your journey
