Animation shows instantaneous and average velocities in a position time graph. In Graph 1 an object starts accelerating from rest , travels uniformly and then comes to rest. In Graph 2 position time graph of an oscilating object is shown. Graph 3 is for a body projected vertically upwards. Check to see if instantaneous and average velocities become equal at any moment. In Graph 4 an object starts accelerating from rest , and then comes to rest.
Average velocity is the slope of the yellow line and Instantaneous velocity is the slope of the cyan line.
Mouse down / touch operations:
Top left half and top right half decrease/increase position rapidly.
Bottom left half and top right half decrease/increase position slowly.
