Forces are interactions that cause changes in motion from "summary" of Physics 11 by British Columbia. Schools Department. Curriculum Development Branch
Forces play a crucial role in the world of physics. They are interactions that can lead to changes in an object's motion. This means that forces can cause objects to speed up, slow down, change direction, or even remain at rest. In essence, forces are what make things move. When discussing forces, it is important to understand that they can come in different forms. For example, there are contact forces, such as friction or tension, which occur when two objects are in direct physical contact with each other. On the other hand, there are also non-contact forces, such as gravity or magnetic forces, which can act on objects without any physical contact. Furthermore, forces are typically describ...
