Physics

After this lesson, you should be able to:

  • Describe vertical projectile motion in words, diagrams, graphs and equations
  • Understand that an object is free-falling if the only force acting on it is the force of gravity
  • Explain the concept “time symmetry” as applied to free fall
  • Use equations of motion to determine position, velocity and displacement of a projectile at any given time
  • Draw the position-time, velocity-time and acceleration-time graphs for 1D projectile motion
  • Given position-time, velocity-time or acceleration-time graphs determine position, velocity and displacement of a projectile at any given time
  • Given position-time, velocity-time or acceleration-time graphs describe the motion of the object
