Question

Explain this

Q.1 Define following terms
(a) Uniform Acceleration
(b) Retardation
(c) Average Velocityween following terms
(a) Distance and Displacement​

Answer 1

Answer:

(a)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.

(b)Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays.

(c)The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a vector quantity. The SI unit is meters per second.

(d)Distance is the length of the path taken by an object whereas displacement is the simply the distance between where the object started and where it ended up. For example, lets say you drive a car. You drive it 5 miles east and then 3 miles west.

Answer 2

Uniform Acceleration:-

Translation: If an object's speed (velocity) is increasing at a constant rate then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn't have uniform acceleration.

Retardation:-

Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays.

Average velocityween following terms:-

The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a vector quantity. The SI unit is meters per second.

Distance and Displacement:-

Distance is the measure of “how much ground an object has covered during its motion” while displacement refers to the measure of “how far out of place is an object.” In this article, let us understand the difference between distance and displacement.
