Inclined Plane - 1-D Motion

Lab Summary

Use a motion sensor to determine position, velocity, and time for an object with constant acceleration and derive mathematical relationships between them.

Theory

Kinematics is the study of the motion of objects. In the AP Physics curriculum, there are three kinematics equations. Two of the three kinematics equations are derived in this experiment. For a cart accelerating down an incline, design and conduct an experiment that explores:

  • Position and time for an object with constant acceleration and then uses that relationship to derive a mathematical relationship between the two.
  • Velocity and time for an object with constant acceleration and then uses that relationship to derive a mathematical relationship between the two.

Method

Students gain experience conducting the following procedures:

  • Releasing a cart from rest down an incline.
  • Graphing the position versus time data of the cart.
  • Linearizing the subsequent data to derive one of the kinematic equations that describes the quadratic relationship between position and time.
  • Determining the velocity at different points of the position-time graph.
  • Creating a graph of velocity versus time to derive another kinematic equation.
