Question

Draw a velocity-time graph of a object moving with uniform retardation​

Answer 1

Answer:

Velocity–Time graphs present the motion of an element by presentation the changes of velocity with reference to time. The law is that the slope of the line on a velocity-time graph reveals practical information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

Velocity-time graphs are used to explain the motion of objects which are moving in a straight line. They can be used to demonstrate acceleration and to work out displacement.

Velocity-time graph In case of uniform retardation and non-uniform acceleration

Velocity-time graph (In case of uniform retardation): There will always be initial velocity for uniform retardation. In this case, also the graph will be a straight line. But its slope will be negative [Figure]. A negative slope means retardation. The slope of the straight line becomes equal to the uniform retardation. Finally, the body comes to rest i.e., its velocity becomes zero.

An object is said to be moving with uniform deceleration or retardation if it reduces its velocity by an equivalent amount in equivalent intervals of time. It is also known as uniform retardation. It is the acceleration in which the object changes its velocity with equivalent intervals of time. The angle of the velocity-time graph of an object moving with the uniform diminishing velocity with uniform acceleration is a downwards instantly line. The straight downward angle shows the decreasing velocity with uniform acceleration, i.e. retardation.
