What are positive and negative acceleration in straight line motion?

Text Solution

Verified by Experts

If speed of an object increases with time, its acceleration is positive. (Acceleration is in the direction of motion) and if speed of an object decreases with time its acceleration is negative (Acceleration is opposite to the direction of motion).
