Introduction
In physics, the magnitude of a force is a measure of how strong or powerful the force is. It can be expressed in newton (N), pound (lb), or other units. In this physics demonstration, you will learn what the net force on a car is and how to calculate it.
The Net Force on a Car
The net force on a car is the force that acts on the car and is exerted by the Earth’s gravitational pull. The net force is calculated by subtracting the weight of the car from the weight of the object being pulled.
The Resulting Magnitude of the Net Force on the Car
The net force on a car is a vector that points in the opposite direction of the car’s motion. The magnitude of the net force is determined by the mass and acceleration of the car, as well as the magnitude of the external forces acting on it. The net force is always directed perpendicular to the direction of motion.
Conclusion
The magnitude of the net force on a car is primarily determined by three factors: mass, distance, and velocity. The more mass a car has, the more gravity will pull on it, while the greater the distance between the car and the object pulling on it (in this case, the net force), the weaker that force will be. Velocity also plays a role in determining how strong a net force is; as velocity increases, so does the potential for kinetic energy to be converted into physical momentum (i.e., speed).
