Question

Problem
Which of the following statements is true of a body that accelerates uniformly? Explain your
answer.
a. Its rate of change of position with time remains constant.
b. Its position changes by the same amount in equal time intervals.
c. Its velocity increases by increasing amounts in equal time intervals.
d. Its rate of change of velocity with time remains constant.​

Answer 1

Explanation:

The acceleration of a body is defined as the rate of change of velocity per unit time. Its mathematical form is given by :

$a=\dfrac{v-u}{t}$

Here,

u is initial speed of a body

v is final speed

t is time taken

Uniform acceleration means that the velocity of an object changes by an equal amount in every equal time period. Hence, the correct option is (c) " Its velocity increases by increasing amounts in equal time intervals".
