Brilliant! The Earth

**always**exerts a force on every object. The force is given by the formula \(W = m g\). This doesn't change.**Never**.So, in this case, we see that

This force is called the

In geometry, normal means

**even though**the Earth is exerting a force on the object, the**Net Force**is \(0\). In other words, there is another force being exerted on the object in the opposite direction that cancels Earth's force.This force is called the

**Normal Force**. The normal force is a force a surface exerts on an object resting on it. The surface exerts just enough force to cancel the force being exerted downwards.In geometry, normal means

**perpendicular**. This force is called the normal force because it acts**perpendicular to the surface**.
