The students should understand the qualitative effect of fluid resistance on projectiles, including time of flight, trajectory, velocity, acceleration, range and terminal speed.

Experiments

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

Terminal Velocity

Experiment #6 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 falling object that experiences significant air drag.
  • Analyze a velocity vs. time graph for evidence that the object has reached terminal velocity.
  • Evaluate the Fdrag = –bv model for air drag force.
