 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Velocity of a particle is defined as the rate of change of displacement with.
 A Direction B Speed C Acceleration D Time
Explanation:

Detailed explanation-1: -Velocity: The rate of change of displacement of an object (displacement over elapsed time) is velocity. Velocity is a vector since it has both magnitude (called speed) and direction.

Detailed explanation-2: -The rate of change in displacement is referred to as velocity. In general, the velocity of an object changes during its motion. It is also called the first-order derivative of displacement with respect to time. It can be expressed as v = d x d t .

Detailed explanation-3: -Rate of change of displacement with time is called Velocity.

Detailed explanation-4: -The rate of change of velocity is called acceleration. Acceleration is the ratio of change in velocity with time. The SI unit of acceleration is m/s2.
