Observe the following v-t graphs and explain the type of force acting in the cases given:

Question

Philoid · Accepted Answer

Slope in the velocity versus time graph is acceleration and hence it is due to application of force.

a) . The slope is constant, so the force is constant and is acting in the direction of motion.

b) . The force acting on the object is zero because there is no velocity change.

c) . The slope is constant, so the force is constant and is acting opposite to the direction of motion.
