Question

the position time graph of a moving particle is shown the instantaneous velocity of the particle is negative at the point

Answer 1

at point c as it is decresing

Answer 2

Answer:

The velocity will be negative at point C.

Explanation:

Velocity is defined as:

The velocity is the rate of change of the position of the particle.

The unit of velocity is m/s and it is a vector quantity.

It has a magnitude and direction.

$v = \dfrac{ds}{dt}$

The point where the slope in the graph is negative, at that point the velocity will be negative.

According to the graph,

The particle moves from A to B with positive velocity, B to C with negative velocity and C to D with positive velocity.

At the point C, the slope is negative.

Hence, The velocity will be negative at point C.
