Question # 1

What is meant by positive and negative acceleration?

  • Ans 1: Positive acceleration:
    Acceleration of a body is positive if its velocity increases with time.
  • Ans 2: Negative acceleration:
    Acceleration of a body is negative if velocity of the body decreases.

Question # 1

A body is moving with uniform speed

  • Ans 1: Velocity of a body has magnitude as well as direction. For a body to more with uniformvelocity it speeds as well as its direction should remain the same Thus it can only me possible if a body is moving in a straight line with constant speed, then its velocity will also be uniform i.e if a body does not change its direction.
