Motion under gravity
Here are some helpful tips for motion under gravity:
Use your Kinematic equations!
If an object is dropped, then initial velocity = 0.
Acceleration due to gravity is 9.81. The sign (+ or -) depends on which direction you have labeled positive.
Horizontal component of your initial velocity when (e.g. for a ball being kicked) stays the same and does not slow down.
