Question

What information is needed to calculate acceleration?

Answer 1

The correct answer to the question is : B) Change in velocity and time.

EXPLANATION:

Before going to answer this question, first we have to understand acceleration of an object.

The acceleration of an object is defined as the rate of change of velocity i.e the change in velocity per unit time.

Mathematically acceleration a = $\frac{dv}{dt}$

dv is the change in velocity, and dt is the time taken by an object.

Hence, change in velocity and time are taken in order to calculate the acceleration of an object.

Answer 2

B change in velocity and time

(metres per second) per second
