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
