Question

What is accelerated motion? Explain with necessary graph, uniformly accelerated linear motion in one dimension. Give two examples of each.

Answer 1

It is the rate of change of velocity with time. The only two ways to accelerate is by changing the speed or change in direction or change both. It is a vector quantity. If the velocity of the object increases with time, its acceleration increases. If the velocity of an object decreases with time, its acceleration is negative.


This type of motion is called accelerated motion

Answer 2

Explanation:

Accelerated motion :

The acceleration is the rate of change of velocity of the object. it is a vector quantity and its unit is m/s².

In mathematical terms,

$a =\dfrac{dv}{dt}$

Uniformly accelerated :

When the acceleration of an object throughout the motion is uniform it is called uniform acceleration.

Example :

1. The motion of free falling object.

2. The motion of an object rolling down an inclined plane.

When the velocity of an object increases with the time then the motion is called uniform accelerated.

We need to draw the graph of uniformly accelerated linear motion in one dimension.
