Assertion: A negative acceleration of a body can be associated with a 'speeding up' of the body. Reason: Increase in speed of a moving body is independent of its direction of motion.

Assertion : A body can be at rest even when it is under the action of may number of external forces Reason : Because vector sum of the all external forces is zero .

Assertion : An object may have varying speed without having varying velocity. Reason : If the velocity is zero at an instant, the acceleration may not be zero at that instant.

Assertion: A body moving with constant acceleration always travels equal distance in equal time intervals. Reason: Motion of the body with constant acceleration is a uniform motion.

Assertion :- A particle has positive acceleration it means that its speed always increases. Reason :- Acceleration is the rate of change of speed with respect to time.

Assertion :- In equilibrium net force on the body is zero. Reason :- A body in equilibrium must be at rest.

The average velocity of a particle moving on a straight line is zero in a time interval. Assertion :- It is possible that the instantaneous acceleration is never zero in the interval. Reason :- It is possible that the instantaneous velocity is never zero in the interval.

Statement 1: Assertion : A vector can have zero magnitude if one of its rectangular components is not zero. Statement 2: Reason : Scalar product of two vectors cannot be a negative quantity.
