To consider after you have investigated Newton's Laws:
Why did Newton, an Englishman, write in Latin?
Who would be able to read his Principia Mathematica? Is this limited access fair? Why/whynot?
Newton's First Law
​
An object either remains at rest or continues to move at a constant velocity, unless acted upon by a force
​
​
​
Sum of forces = 0 Change in velocity dv/dt = 0
An object that is at rest will stay at rest unless a force acts upon it.
An object that is in motion will not change its velocity unless a force acts upon it.
The property where massive bodies resist changes in motion is called inertia

An object that is at rest will stay at rest unless a force acts upon it.

Newton's Second Law
​
The force F on an object is equal to the mass m of that object multiplied by the acceleration a of the object:
​
F = ma
Force and acceleration are vector quantities—they have both magnitude AND direction
​
The second law states that the rate of change of momentum, p (unit kg.m/s), of a body is directly proportional to the force applied, and this change in momentum takes place in the direction of the applied force
​
​
​
​
​
​
​
Mass = amount of matter in an object
Weight = force of gravity (acceleration due to gravity) acting on a body of mass m
So weight (in newtons, N) = m x acceleration due to gravity
= mass x 9.8 m/s^2
Newton's Third Law
​
When a body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first
​
The third law states that all forces between two objects exist in equal magnitude and opposite direction: if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal in magnitude and opposite in direction: FA = −FB. The third law means that all forces are interactions between different bodies

If you throw a ball on Earth, standing on the ground, there is no measurable effect to the much more massive Earth—but if you were at an ice rink on ice skates, you would move backwards as you threw the ball forwards
Limits of the laws—they work well in macroscopic, moderate Earth conditions
Newton’s Laws are less useful in certain circumstances, in very small scales, at very high speeds, or in very strong gravitational fields
