Student Must Know…
  1. Key Words
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
  1. Inertia
  2. F = m x a
  3. 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.

Students Must be able to do…
-Calculations for force when given mass and acceleration.
-F=ma (force = mass x acceleration).
-Describe the motion of an object when no force acts on it.
-Complete a graph of motion.
-Draw a distance vs time, velocity vs. time, and acceleration vs. time motion graphs.
-Interpret all of the above graphs.
-Calculate weight using F=ma with “a” being the acceleration due to gravity.
