Physics

The plan:

  • Video clip of the day
  • 2D motion
  • Introduction to Projectiles
    • Even projectiles
    • 2D motion questions.
  • Work on review practice quiz.

Important Assumptions:

  • No air resistance.
  • Object does not hit anything while in flight.
  • Ground is level unless stated differently.
  • You are on Earth unless stated differently.
  • Gravity field is constant.
  • The object is not moving at light speed.

Projectile Motion:

X - component:

  • Initial velocity in x?
  • Final velocity in x?
  • Final displacement in x?

Example projectile question:

  • A ball is hit off the ground at 53 degree angle of elevation. Initial velocity is 30m/s. Assume the surface is level. - A) When does the ball reach maximum height? - B) How long was the ball in the air? - C) How far did the ball go (range)?

Max Height:

How long was the ball in the air?

Range?

  • An object on Earth is moving at 400m/s. It is launched at a 25 degree angle. - How long (in seconds) was it in the air? - What was the total range of this projectile?
