Newton's Laws
Newton's Second Law of Motion
Force = Mass x Acceleration
Acceleration
is defined as a change in velocity
Examples
Speeding up
Slowing down
Turning
or Force = rate of change in Momentum
Momentum
is defined as
Mass x Velocity
Mass
is defined as
The amount of material within an object
Isn't the same as Weight
Weight
is defined as
1 more item...
Volume
Is defined as
the measure of the physical space an object occupies
Density
is defined as
Mass/Volume
1 more item...
The change of motion of a body is proportional to and in the direction of the force acting on it
Newton's Third Law of Motion
For every force, there is always an equal and opposite reaction force
Conservation of Momentum
Momentum is transferred from one object to another
Conservation of Angular Momentum
A rotational version of Newton's Laws: an object that is spinning will continue spinning until an in-spinny force acts on it
Mass x Velocity x Radius
Newton's First Law of Motion
Velocity
is defined as both
Speed
Example: car speedometer
Units: m/s
Direction
Examples
West
East
An object moves at a constant velocity
unless a net force
acts to change its speed or direction
Examples of a force
Gravity
Push
Pull
