Newtons First Law of Motion

Lab Summary

Use a motion sensor and force sensor to determine how the change in an object’s motion is related to the force (push or pull) applied to the object.

Theory

Students discover how the change in an object’s motion is related to the force (push or pull) applied to the object. Students investigate the nature of force and inertia while they:

  • Recognize that a force is a push or a pull
  • Recognize that forces have magnitudes (strengths) and directions
  • Discover that a force applied to an object will change the object’s motion
  • Describe the key idea of Newton’s first law of motion in their own words

Method

Students gain experience conducting the following procedures:

  • Students use a force sensor to measure the force applied to a cart. They use a motion sensor to measure the cart’s motion. By comparing the data from the force sensor with data from the motion sensor, students demonstrate Newton’s first law of motion:
“Every body persists in its state of rest or of uniform motion in a straight line unless it is compelled to change that state by forces impressed on it.” —Sir Isaac Newton
  • Setting up the equipment and work area to measure position and force on a cart
  • Recording position versus time and force versus time for a cart in motion and displaying the data in a graph
  • Recording both force and position versus time, simultaneously, and displaying the data in a graph
  • Using math and verbal skills to analyze graphical data and express Newton's first law of motion in students' own words
