Velocity and Motion
-The difference between speed (only a number and a unit) and velocity (a number, unit, and direction).

-Acceleration due to gravity = 9.8 m/s2 in free fall motion.

-When to use m/s as a unit à velocity.
-When to use m/s2 as a unit à acceleration.
-When to use g and kg as a unit à mass.
-The symbol “v” = velocity.
-The symbol “a” = acceleration.

Force: Newtons 3 Laws

Inertia

F = m x a

Every action has equal and opposite reaction

-The symbol “F” = force.
-The symbol “m” = mass.
-When to use N as a unit à force.

Momentum:p = m x v

-The symbol “P” = momentum.
-When to use kgm/s as a unit à momentum.
