Question

in a velocity time graph acceleration would be least when _________________________​

Answer 1

Answer:

The area under the velocity/time curve is the total displacement. If you divide that by the change in time, you will get the average velocity. Velocity is the vector form of speed. If velocity is always non-negative, then average velocity and average speed are the same.

Answer 2

In a velocity-time graph, acceleration would be least when the graph is parallel to the x-axis.

• In a velocity-time graph, acceleration is given by the slope of the graph.

• Acceleration = $\frac{dv}{dt}$

• When the sope is positive, acceleration is positive, i.e. velocity of the object increases.
• When the slope is negative, acceleration is negative, i.e. object is retarding.
• When the graph is parallel to the x-axis, slope = 0, i.e. body is moving with uniform velocity.
