Question

When is average velocity equal to instantaneous velocity?

Answer 1

Answer:

when body moves with uniform velocity

Explanation:

Answer 2

Answer:

The slope of displacement/distance vs time graph gives velocity/speed

For average velocity to be equal to instantaneous speed

• If the graph is straight line then the slope will be equal for both average velocity and instantaneous velocity for given displacement/distance vs time graph.So,for straight line acceleration should be zero.
• if the slope of tangent drawn from displacement/distance vs time graph curve is the equal to slope of line for average velocity.
