Forces #3

Today I will be talking about force for the third time. Again force is defined as a push or a pull. Force is measured in newtons which kilograms meters per seconds squared. this time I will be focusing on Newton's third law. It states for every action there is an opposite and equal reaction, this law is also known as the action reaction. For example while you are on earth and you jump upward, the gravitational pull of the earth pushes you back down. Therefore the forces acted upon you are balanced. A balanced net force is a force that is in equilibrium so that it is not accelerating. We are able to show these time of equations with free body diagrams. This is resembled by a circle, being the object, and arrows which represent the forces being exerted on it.
