Force, Mass, Acceleration

Newton's law of motion describes the relationship of force, mass, and acceleration. Write the equation.

• M=F/A

• F=MA

• A= F/M

• All of the above

A car accelerates from rest on a straight road. What does the car's acceleration depend on?

• Its color and shape

• Its mass and the force applied to it

• Its volume

• Its temperature

Answer explanation

An object's acceleration depends on its mass and the force applied to it, not its color, shape, volume, or temperature.

Imagine you're pushing a shopping cart. What happens to the cart's acceleration if you push it with more force?

• It decreases

• It stays the same

• It increases

• It stops

Answer explanation

When the force applied on an object increases, its acceleration also increases according to Newton's second law of motion.
