Question

velocity time graph of ab object is given below the object it has a. uniform velocity b. uniform speed c. uniform retardation​

Answer 1

Answer:

ANSWER

Acceleration of body is given by slope of velocity time graph.

The initial velocity is intercept of velocity OA. Since the slope of graph is negative Hence the body is moving with negative acceleration or Initial velocity OA and is moving with uniform retardation.

Answer 2

Explanation:

Uniform retardation

The slope of the line on a velocity - time graph gives the information about the Acceleration of the body.

If the acceleration is zero , then the slope is zero(horizontal line)

If the acceleration is positive , then he slope is positive(upward slope)

If the acceleration is negative , then the slope is negative(downward slope)

The negative acceleration is also called as Retardation and the object moving in negative direction is said to be retarding

Hence  the velocity-time graph shows the uniform retardation of the object.
