Question

When the acceleration of particle is positive and is increasing, then its velocity must be positive.

• A. True
• B. False

Answer 1

The correct option is B False

Acceleration:

• It is the rate of change of velocity with respect to time.
• It is a vector quantity.

Velocity:

• It is the rate of change of the object's position with respect to the frame of reference and time.
• It is a vector quantity.

The given statement is not true because,

• The acceleration of a particle is positive and increasing but velocity may be negative at the instant time taken as origin.

Hence, the given statement is false.
