Newton's 3 laws
1, 2, & 3
1st law (Law of inertia): An object in motion stays in motion unless equal or opposite force is acted on it
This means an object in rest will stay at rest, 1 example is a soccer ball sitting on the lawn at rest until it is kicked. Another example is pulling a card from the top of a cup with a coin on it.
2nd Law: the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
F=ma is the formula to find the acceleration of an object.
