Experiments

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

Graph Matching

Experiment #1 from Physics with Vernier

  • Analyze the motion of a student walking across the room.
  • Predict, sketch, and test position vs. time kinematics graphs.
  • Predict, sketch, and test velocity vs. time kinematics graphs.

Ball Toss

Experiment #6 from Physics with Vernier

  • Collect position, velocity, and acceleration data as a ball travels straight up and down.
  • Analyze position vs. time, velocity vs. time, and acceleration vs. time graphs.
  • Determine the best-fit equations for the position vs. time and velocity vs. time graphs.
  • Determine the mean acceleration from the acceleration vs. time graph.

Determining g on an Incline

Experiment #4 from Physics with Vernier

  • Use a Motion Encoder System to measure the velocity and acceleration of a cart rolling down an incline.
  • Determine the mathematical relationship between the angle of an incline and the acceleration of a cart rolling down the incline.
  • Determine the value of free fall acceleration, g, by using an extrapolation on the acceleration vs. sine of track angle graph.
  • Determine if an extrapolation of the acceleration vs. sine of track angle is valid.
