Physics

Describe the trajectory of an object undergoing projectile motion within the Earth’s gravitational field in terms of horizontal and vertical components

solve problems and analyse information to calculate the actual velocity of a projectile from its horizontal and vertical components using: v = u + at v2 = u2+ 2as s = ut + ½ at2 (N.B. change to component versions)

Caroline Chisholm College

Physics

Perform a first-hand investigation,gather information andanalyse data to calculate initial and final velocity,maximum height reached, range,and time of flight of a projectile, for a range of situations by usingsimulations, data loggers andcomputer analysis

vx= ux+ axtvx2 = ux2+ 2axDxDx = uxt + ½ axt2

vx= uxvx2 = ux2Dx = uxt

vy= uy+ aytvy2 = uy2+ 2ayDyDy = uyt + ½ ayt2
