  • P5c - Projectile Motion
    • Gravity
      • If air resistance is ignored, the only force acting on the projectile is gravity.
      • Gravity can only cause a downward acceleration and can only affect the object's vertical velocity
    • E.g. a stone kicked off a cliff will follow a curved trajectory as it falls to the ground/sea.
      • The Earth's gravitational field pulls it towards the ground
      • The curve is described as parabolic.

    • When cannon balls or missiles are fired into the air, they are called projectiles
    • If a projectile is projected horizontally, two things could happen...
      • The object's horizontal velocity (a vector) will stay the same i.e. (constant)
      • The object will accelerate towards the ground so its vertical velocity (a vector) will increase steadily.
