Define Uniform Velocity and Uniform Acceleration

Answer: Velocity can be defined as the rate of change in an object’s position with respect to a given time frame and reference. Velocity is a vector quantity while speed is a scalar quantity. Vector means it has both magnitudes as well as direction while scalar means it has only magnitude. The Standard unit of the vector is a meter per second (m/s). If there is any change that occurs in both magnitude and direction, then the object becomes accelerated. 

Acceleration can be defined as the change in velocity per unit of time. A change in velocity requires the application of a push or a pull force. It is a vector quantity and must have a direction. The symbol used to represent acceleration is “a” and its SI unit is m/s/s or m/s².

What are uniform velocity and uniform acceleration?

• Uniform acceleration can be defined as constant, unchanging acceleration. When an object is uniformly accelerated, the speed of the entire time interval that the acceleration occurred over can be represented by the average velocity of that time interval.

Initial velocity defines how fast an object moves when gravity applies force on a given object. On the other hand, the final velocity is that vector quantity that measures the speed as well as the direction of a moving body once it has reached the point of its maximum acceleration. A body is said to be moving with a uniform velocity when it covers the same distance in equal time intervals. In this case, both magnitude and direction would not change with time. On the other hand, when an object travels with an increasing velocity at an equal interval of time, then we can say that the body is moving with uniform acceleration.
