Question

A body is moving under the action of a constant force.Then draw the graph between its mass and acceleration

Answer 1

Explanation:

Instantaneous Power delivered by a force is P=

F

.

v

As the body is moving along a straight line and the force is constant, we can write P=Fv

For a constant F, acceleration a will be constant (say k).

If initially, the body is at rest, we can write velocity v=kt and P=Fkt. As F and k are constants, graph of P vs t will be a straight line passing through origin.

So, graphs (B) can represent the plot of P vs t
