20: Projectiles

#20.1

Projectiles

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

Position and velocity of a projectile

Know how to find the position and velocity at any time of a projectile and find range and maximum height.

#20.3

Find the initial velocity of a projectile

Be able to find the initial velocity of a projectile given sufficient information.

#20.4

Find equation of trajectory of a projectile

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

Solve problems involving projectiles

Be able to solve simple problems involving projectiles.

Excludes: Maximum range on inclined plane. Bounding parabola.
