The students should understand the behaviour of projectiles in the absence of fluid resistance, and the application of the equations of motion resolved into vertical and horizontal components


Here are experiments our science specialists have selected to support this IB* topic.

Projectile Motion (Photogates)

Experiment #8A from Physics with Vernier

  • Measure the velocity of a ball using two Photogates.
  • Apply concepts from two-dimensional kinematics to predict the impact point of a ball in projectile motion.
  • Take into account trial-to-trial variations in the velocity measurement when calculating the impact point.

Projectile Motion

Experiment #4 from Vernier Video Analysis: Motion and Sports

In this experiment, you will

  • Use video analysis techniques to obtain position, velocity, and time data for a projectile.
  • Analyze the position vs. time and velocity vs. time graphs for both the horizontal and vertical components of the projectile’s motion.
  • Create and analyze your own video of an object undergoing projectile motion.
