Front

How do you calculate mass using force and acceleration?

Back

Mass can be calculated using the formula: Mass = Force / Acceleration.

Front

If a car accelerates at 3 m/s² with a force of 600 N, what is its mass?

Back

The mass of the car is 200 kg.

Front

What is the formula to calculate acceleration?

Back

Acceleration = Force / Mass.
