Question

The force of an object (f) is equal to its mass (m) times its acceleration (a). Thus, the formula for calculating force is f = ma.

Based on this information, which of the following equations would be used to calculate acceleration?

A. a = fm
B. a = f ÷ m
C. a = f + m
D. a = f − m

Answer 1

`a = f / m`

Step-by-step explanation

The force of an object (f) is equal to its mass (m) times its acceleration (a). Thus, the formula for calculating force is f = ma.

We want to solve this relation for 'a'.

We need to divide both sides by 'm'

This implies that,

`(f)/(m) = (ma)/(m)`

We cancel out the common factors on the right hand side to obtain:

`(f)/(m) = a`

We can rewrite this as:

`f / m = a`

Or

`a = f / m`

The correct choice is B.
