Question

Define the following terms:-

(i) Uniform Acceleration

(ii) Non-uniform Acceleration

(iii) Angular Acceleration​

Answer 1

Answer:

1. If an object's speed (velocity) is increasing at a constant rate then we say it has uniform acceleration

2.Non-uniform acceleration constitutes the most general description of motion.

3.The angular acceleration is the time rate of change of the angular velocity and is usually designated by α and expressed in radians per second per second. For the case in which the angular velocity is uniform (nonvarying), θ = ωt and α = 0.

Answer 2

Answer:

Explanation:

I) Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period. A frequently cited example of uniform acceleration is that of an object in free fall in a uniform gravitational field.

II)It means that the acceleration is constant, and neither increasing nor decreasing. Non-Uniform means that the acceleration is not uniform. Uniform acceleration is change of equal velocity in equal intervals of time. Non Uniform acceleration is change of non-equal velocity in equal intervals of time.

III)It is the rate of change of angular velocity with a time of an object in motion. It is a quantitative expression of the change in angular velocity per unit time. ... The acceleration vector, magnitude, or length is directly proportional to the rate of change in angular velocity.
