KINEMATICS
VERTICLE PROJECTILE MOTION
GRAVITATIONAL FORCE (Fg)
The earth exerts a gravitational force of attraction on all objects that have
mass. The force is also known as weight
Fg = m x 9.8
FRICTION IN THE ATMOSHERE (Ff)
Friction always acts in the opposite direction of motion
FREE FALL
A free falling object only experiences a force of gravity
Free falling objects do not experience friction (Ff)
Free falling objects accelerate at 9.8m.s-2
ACCELERATION DUE TO GRAVITY (g)
The acceleration of any mass near the surface of the earth is 9.8m.s -2
Δvv
a = Δvt
