#20.1
Be able to model motion under gravity in a vertical plane using vectors. Be able to formulate the equations of motion of a projectile using vectors.
Standard modelling assumptions for projectile motion are as follows.
• No air resistance.
• The projectile is a particle.
• Horizontal distance travelled is small enough to assume that gravity is always in the same direction.
• Vertical distance travelled is small enough to assume that gravity is constant.
[Excludes: Calculations involving air resistance.]

#20.2
Know how to find the position and velocity at any time of a projectile and find range and maximum height.
#20.3
Be able to find the initial velocity of a projectile given sufficient information.
#20.4
Be able to eliminate time from the component equations that give the horizontal and vertical displacement in terms of time to obtain the equation of the trajectory.
#20.5
Be able to solve simple problems involving projectiles.
