A force is a push or a pull. When the wind pushes a sailboat through the water, it is exerting a force. When gravity pulls an apple towards the ground, that is a force as well.
We are going to study eight type of forces. Name the forces and draw them. That will help you to understand them better.
Some of the forces that we will see we have already studied them, like the magnetic force or the gravity force. Here is more information.
Drag force is the same as air resistance or fluid resistance.
It happens in ships as well.
