Question

The rate of change of displacement With time is called ?​

Answer 1

Rate of change of displacement with time is called velocity

additional information:-    

what is Velocity?

• (Velocity is defined as the rate of change of displacement.

• $\boxed{\bold{\sf{Velocity =\dfrac{Change\:in\:displacement}{Time}}}}$

• Velocity is a vector quantity, ie it has magnitude as well as direction.

• The SI unit of velocity is m/s

• The dimension of velocity is [L]

• The values of velocity can be positive, negative and zero.

what is  Speed?

• It is defined as the rate of change of distance.

• $\boxed{\bold{\sf{Speed =\dfrac{Change\:in\:distance}{Time}}}}$.

• speed is a scalar quantity ie it has magnitude but no direction.

•  The SI unit of speed is m/s

•  The dimension of speed is [L]

• The value for Speed can be positive and zero but not negative.

Answer 2

Explanation:

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.

Acceleration: The rate of change of velocity is acceleration. Like velocity, acceleration is a vector and has both magnitude and direction

Newton's Laws of Motion

First Law:

First Law:An object at rest or traveling in constant, straight-line motion (a state of no acceleration) will remain at a constant velocity unless acted upon by an outside force.
