Mechanics External Term 1

Week one: Pgs 127 - 130 Displacement, Velocity and Acceleration

Week two: Pgs 131-134 Graphs and Kinematics

Week three: Pgs 135 - 139 Vectors and Relative Velocity

Week four: Pgs 140 - Motion under Gravity and Projectile Motion.

Week five: Pgs - End of Chapter Review

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.
