Define a scalar quantity
A quantity that has magnitude, no direction
State Newtons 1st law of motion
An object in motion will stay in motion, an object at rest will stay at rest, unless they are acted on by a force.
Calculating the slope of a distance-time graph tells you what?
Velocity !
Define a vector quantity
A quantity that has both magnitude and direction
State Newtons 2nd law
F = m x a
Calculating the slope of a velocity-time graph tells you what?
Acceleration!
State Newtons 3rd Law
For every action there is an equal and opposite reaction
