Meters per second squared (m/s
kilogram times meters second squared (kg x m/s
Convert 60km per hour to SI units.

Newton's first law
The Law of Inertia:
A soccer ball at rest in a field
Objects at rest stay at rest
Every object in a state of uniform motion tends to remain in that state of
motion unless an external force is applied to it.
Newton's Second Law
Force and acceleration
Soccer ball being kicked
Newton's Thrid Law
Action and Reaction
Kayak paddles pushing water
For every force there is an equal and opposite reaction
Velocity and Acceleration
: Speed together with direction of motion
: Rate at which velocity is charging. May be magnitude, direction or both.
Both are vectors
Law of Conservation and Momentum
In the absence of a net external force the momentum of an object or system of objects is unchanged.
(Object at rest stays at rest)
Impulse= change in momentum
Two projectiles bounce off each other; apart/ seperation
Projectiles hit and stick; same velocity after collision
Can be vertical or horizontal
: Object goes around itself
: Goes around something else
