Uniform Acceleration: It is a type of acceleration where an object’s velocity changes by the same amount over equal intervals of time. In other words, the acceleration remains constant over time. An example of uniform acceleration is a freely falling object under the influence of gravity. The acceleration due to gravity near the Earth’s surface is approximately 9.8 meters per second squared (m/s²). This means that any object that falls freely near the surface of the Earth will experience a uniform acceleration of 9.8 m/s² downward.

Formula of Uniform Acceleration

The equation can be expressed as:

v = u + at

Where,

• “v” is the final velocity of the object,
• “u” is the initial velocity of the object,
• “a” is the acceleration,
• “t” is the time taken for the velocity to change.

This equation is known as the “equation of motion” for uniform acceleration. It can be used to calculate the final velocity of an object under uniform acceleration given its initial velocity, acceleration, and the time it has been accelerating for.

For example, if a car is traveling at an initial velocity of 20 m/s and accelerates at a rate of 5 m/s² for 6 seconds, the final velocity can be calculated as:

v = u + at = 20 m/s + (5 m/s² x 6 s) = 50 m/s

This means that after accelerating at a uniform rate of 5 m/s² for 6 seconds, the car would be traveling at a velocity of 50 m/s.
