$\huge\bold{Question}$

define the uniform Acceleratio with one example

$\huge\bold{Answer}$

To understand the concept of uniform acceleration we need to understand the concept of Acceleration first.

✍ Acceleration

Acceleration is the rate of change of velocity with time.

It is defined as change of velocity of body per unit time.

SI unit of acceleration is m/s²

It is Vector Quantity.

Acceleration = Change in velocity / time

= Final velocity - Initial velocity / time

= v - u / t

✍ Types of Acceleration

1. Uniform Acceleration

If the velocity changes in equal amounts in equal time of intervals and the object travels in a straight line than the uniform acceleration take place.

Example - A ball rolling down a slope

2. Non-uniform Acceleration

If the velocity changes in an equal amount in unequal intervals of time and object travels in straight line then non uniform acceleration take place.

Example - If a car covers 10 meters in first two seconds, and 15 meters in next two seconds.

✏ Zero Acceleration -

If the change in velocity is zero that is either object is at rest or moving with uniform velocity than zero acceleration will take place.

✏ Positive Acceleration -

When velocity of a body increases then positive acceleration take place.

i.e v > u

✏ Negative Acceleration -

When velocity of a body decreases the negative acceleration take place.

It is in the opposite direction of velocity.

i.e v < u
