Forces & Energy Transfer

Forces & Energy Transfer!

Forces cause the transformation of energy, where one form of energy is converted into another as the force moves an object over a distance. This process is called an energy transformation or conversion, and it adheres to the law of conservation of energy>>, which states that energy cannot be created or destroyed, only changed from one form to another. For example, a car converts the chemical energy in fuel into kinetic energy, and a hydroelectric dam converts the potential energy of water into electrical energy. 

1. What Are Forces?

A force is a push or a pull that can change an object's motion.

Types of Forces

key Ideas

• Forces are measured in newtons (N).

• Net force = total of all forces acting on an object.

• When forces are balanced, motion doesn’t change.

• When forces are unbalanced, the object accelerates.
