Newtons 3 Laws | Three physical laws that, together, laid the foundation for classical mechanics. |
Newtons 1st Law | A body remains at rest or in motion with a constant velocity unless acted upon by an external force. |
Newtons 2nd Law | The rate of change of momentum is proportional to the imposed force and goes in the direction of the force. |
Newtons 3rd Law | Action and reaction are equal and opposite. |
