A group of students are measuring how the acceleration of a mass will change due to a force.
Fudgin [204]

The graph of the plot of acceleration against force is a straight line graph. Option B

<h3>What is the relationship between force and acceleration?</h3>

From the Newton's second law of motion we can derive that; F = ma

F= mass

a = acceleration.

This implies that the acceleration and the mass of a body has a linear relationship. We could then assert that the force is directly proportional to the acceleration with the mass being the constant in the equation.

As such, the force that is imparted to the body is what determines the acceleration and the both increases or decreases linearly. Thus the graph of the plot of acceleration against force is a straight line graph. Option B
