Physics: Forces and Motion

Forces and Motion – What makes objects move the way they do?

8.1 - An object’s inertia causes it to continue moving the way it is moving unless it is acted upon by a force to change its motion.

  • The motion of an object can be described by its position, direction of motion and speed.
  • An unbalanced force acting on an object changes its speed and/or direction of motion.
  • Objects moving in circles must experience force acting toward the center.

C 22. Calculate the average speed of a moving object and illustrate the motion of objects in graphs of distance over time.

C 23. Describe the qualitative relationships among force, mass and changes in motion.

C 24. Describe the forces acting on an object moving in a circular path.
