# 2.1 Motion

## 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.
