Introduction to projectile motion MANDATORY experiment Do write-up in your MANDATORY PRACTICAL INVESTIGATIONS booklet

Syllabus Dot Point perform a first-hand investigation, gather information and analyse data to calculate initial and final velocity, maximum height reached, range and time of flight of a projectile for a range of situations by using simulations, data loggers and computer analysis.

Projectile motion is horizontal & vertical motion at the same time

Vertical Motion a a Uniform downward acceleration (= ‘g’ = 9.8 m/s2 on earth’s surface)

Uniform horizontal velocity Horizontal Motion Uniform horizontal velocity v v v v v v v v

Putting the 2 motions together All vector quantities (r, v, a) add together for x- and y-values Vx Vy V
