# Newtons Laws

### A quick review of Newton's three laws and how they work

What is Newton's First Law An object will continue its current state of motion unless acted upon by an outside force. This law is also known as the Law of Inertia.
What is Newton's Second Law The acceleration of an object is directly related to the net Force acting on it and inversely related to it's mass. F=ma
What is Newton's Third Law For every action there is an equal and opposite reaction.
What is mass? Mass is a mathematical representation of inertia.
Which of Newton's Laws explains the phenomenon that allows you to pull a tablecloth from beneath cups and plates? Newton's First Law
Which of Newton's Laws explains the phenomenon a cannon kicking backwards when fired? Newton's Third Law
Which of Newton's Laws explains fact that pushing a truck with all of your might causes less (if any) acceleration to the truck. Newton's Second Law
An object is being pulled to the east with a force of 40 Newtons at the same time as it is being pulled to the west with a force of 20 Newtons. What is the net Force acting on the object? 20 Newtons east
What is the unit for Force? Newton or kilogram-meter per second squared
What is the acceleration of a 10 kilogram object being propelled by a 20 Newton net force? 2 meters per second squared
