Question

Draw displacement time graph for the following situations
1. When body is stationary
2. when body is moving with uniform velocity
3. when body is moving with variable velocity
​

Answer 1

1. When a body is stationary or at rest, it means that it does not change its position with time. According to Newton's first law of motion, a body continues to remain in the same state of motion or rest until and unless an external unbalanced force acts on it.

2. The acceleration of a body moving with uniform velocity will be zero. Solution: The 'acceleration of a body' moving with uniform velocity will be zero as acceleration is defined as the “rate of change of velocity” per unit time.

3. A body moving on a circular path with constant speed that is undergoing a uniform circular motion has variable velocity. The direction of velocity changes each moment and hence the velocity is not constant.

Answer 2

$\huge \text{Question -}$

Draw displacement time graph for the following situations

1. When body is stationary

When the body is at stationary it means that the body is not moving and for displacement time graph when the body is stationary draw straight line parallel to x axis (time axis) .

2. when body is moving with uniform velocity

When body is moving with uniform velocity it means that the body is moving with constant velocity and for displacement time graph when the body is moving with uniform velocity draw straight line inclined to time axis x axis (time axis) .

3. when body is moving with variable velocity

When body is moving with variable velocity it means that the body is moving with unequal distance is covered in equal interval of time and for displacement time graph when the body is moving with variable velocity draw curve line .
