Forces cause changes in motion from "summary" of Physics 11 by British Columbia. Schools Department. Curriculum Development Branch
The concept that forces cause changes in motion is a fundamental principle in physics. When an object is at rest or in motion, it will remain in that state unless acted upon by an external force. This means that an object will continue on its current path and speed without any interference. However, when a force is applied to an object, it will cause a change in its motion. Forces can be classified into two main categories: contact forces and non-contact forces. Contact forces are exerted when two objects physically touch each other, such as when pushing a book across a table or kicking a soccer ball. Non-contact forces, on the other hand, act at a distance without any physical contact, like gravitational forces or magnetic forces. The effect of a force on an object can be described by Newton's laws of motion. According to Newton's first law, an object will remain at rest or in motion at a constant ...
