Question

please tell me about object moving with variable speed​

Answer 1

Answer:

As per the problem an object is moving with a variable speed and we need to say what will happen to the velocity of that object.

Velocity:

The velocity of an object is defined as the rate of change of its position with respect to a frame of reference and is a function of time and it is a vector quantity as it has both magnitude and direction.

Speed:

Speed is defined as the rate at which an object covers distance. This means an object moving at higher speed can cover a larger distance while a slow moving object will cover a smaller distance. It is scale as it has only magnitude.

As in this problem we are only talking about the magnitude of speed which is variable.

Relation between speed and distance is:

vs=dD

Where,

Velocity = v

Speed = s

Displacement = d

Distance = D
