when
is a motion said to be in 1) uniform acceleration?2) non uniform acceleration?
Answers
Answer:
(i) A body is said to be in uniform acceleration if it travels in a straight line and its velocity increases or decreases by equal amounts in equal time intervals. (ii) A body is said to be in non-uniform acceleration if the rate of change of its velocity is not constant, that is differs in different time intervals. 2.
Uniform acceleration
If an object travels in a straight line and its velocity changes by equal amount in equal interval of time, then the object is said to be moving with uniform acceleration.
For example, a body falling freely from a height towards the surface of the earth.
Non uniform acceleration
If the velocity of an object changes by an equal amount in equal intervals of time, then the object is said to be moving with variable acceleration or non uniform acceleration.
For example, the motion of a football player on the field.
