Force and Motion (Y 10)


Keyword: Mechanics Lab

Demonstration Description:
Purpose of the Experiment:
In this experiment you will study the motion of a cart on a track in response to an applied force. The experiment is intended to help you investigate the following ideas, many of which you may already know.

  • Velocity is the rate of change of an object's position with respect to time, and acceleration is the rate of change of an object's velocity with respect to time.
  • Compute the instantaneous and average velocity from (i) a position vs. time graph of an object's motion and (ii) from a mathematical function describing the position of an object as a function of time.
  • Understand that an object's acceleration may be either constant or may change with time or position.
  • Determine experimentally whether an object moving in one dimension has constant or variable acceleration.
  • Describe mathematically the motion of objects with either constant or variable acceleration; in particular see if you can verify F = ma.
  • Learn how to represent the motion of an object using words, graphs, numerical tables, and equations. Learn to move comfortably among the different ways to represent motion.
