A constant net force acts on a trolley - NSC Physical Sciences - Question 1 - 2017 - Paper 1

According to Newton's Second Law, the formula is given by:

$F = m imes a$

where:

• $F$ is the net force exerted on the object,
• $m$ is the mass of the object,
• $a$ is the acceleration of the object.

From this equation, we can derive:

$a = \frac{F}{m}$

This indicates that the acceleration ($a$) is directly proportional to the net force applied ($F$) and inversely proportional to the mass ($m$) of the trolley. Therefore, the correct answer is:

D - inversely proportional to.
