# Forces and Acceleration

### Force

A **Force** is the push or pull on an object. This means that if I am hitting a rock with a stick, and it goes flying, I am applying force to the rock using the stick. **Net Force **or **N **is the sum of all the forces being applied to an object.

If two kids both hit a stone with the sum of the forces being** 100 N **(100 Net Force)** **and both children are hitting the rock at the same force, then the force of each of the kids is **50 F**.

### Acceleration

When **N **is applied to an object, this said object will change speed. This change is the object's **Acceleration **(**A**). The larger the object, the more **N **is required for it to move faster.

For example, if you want to move a truck at the same speed as a Lamborghini, then you will have to apply more **N **to the truck rather than to the race car because it has a smaller mass than the truck and thus needs less **N **than the bigger vehicle.
