Introduction

Everyone knows that force and motion are related. A stationary object will not begin to move unless some agent applies a force to it. But just how does the motion of an object depend on the forces acting on it? In this experiment you will begin to examine the role that forces play in the motion of an object.

Objectives

In this experiment, you will

  • Collect position, velocity, and time data as a cart is launched by a spring and slowed by friction.
  • Analyze the position vs. time and velocity vs. time graphs.
  • Investigate the effect of varying the friction on the velocity of the cart.
