Motion in two dimensions and projectile motion

Learning objectives

Resolve a displacement, velocity or acceleration vector into perpendicular components using trigonometry, and combine components to find the magnitude and direction of a resultant

Explain why the horizontal and vertical components of projectile motion are independent, with constant horizontal velocity and constant downward acceleration of magnitude g

Calculate the time of flight, range, maximum height and velocity at any instant for a projectile launched horizontally or at an angle, neglecting air resistance

Describe the motion of an object relative to reference frames moving at constant velocity, and calculate relative velocities by vector addition

Create graphs of the horizontal and vertical components of a projectile's position and velocity against time, and explain the shape of each graph
