Question

Why is it called accelerated motion?

Answer 1

Answer:

A point an object moving in straight line is accelerated if it speeds up and slow down.Motion on a circle is accelerated even if the speed is constant,the direction is direction is continually changing..because acceleration has both the maginitude and a direction, it is vector quantity.

Answer 2

•As we know

☆a measure of the Change in the velocity of an object per unit time that is acceleration.

______________________________

》if velocity of an object changes from an initial value u to final value v in time t the acceleration a is

$a = \frac{v - u}{t}$

this kind of motion is known as accelerated motion.

》NOTE - the acceleration is taken to be positive if it is in the direction of velocity and negative when it is opposite to the direction of velocity.
