Term 1 Week 4 2017

Homework
Projectile Motion Worksheet

Use Trigonometry to find your Vertical initial velocity and Horizontal initial velocity component vectors

Projectile Motion follows a Parabolic Path that is Symmetrical about the highest point

Vertical Axis - downward acceleration at g, use kinematic equations

Horizontal Axis - no acceleration due to forces being balanced, use v =d/t

Time, t, is the only scalar (not a vector) so ties both Vertical and Horizontal together

The Vertical and Horizontal Motions are otherwise independant

Term 1 Week 2

Rearranging Kinematic Equations

You need to get familiar with rearranging the Kinematic Equations for each term

Homework: complete p.30-31 1D Kinematic Equations by Thursday 11th Feb

Projectile Motion

All objects fall at the same rate regardless of their horizontal velocity

• Vertical Axis - downward acceleration at g, use kinematic equations
• Horizontal Axis - no acceleration due to forces being balanced, use v =d/t
