Define following terms (a) Uniform Acceleration (b) Retardation (c) Average Velocity
Answers
Answer:
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 velocity= 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.

please mark me as brainlist
Answer:
uniform acceleration : when a body travels in a straight line and it's velocity changes by equal amounts in equal intervals of time , it is said to have uniform acceleration
Retardation:Negative acceleration is known as retardation
Average velocity: it is defined as the total displacement covered divided by total time taken
