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

C 2.                  Describe the qualitative relationships among force, mass and changes in motion.

C 3.                  Describe the forces acting on an object moving in a circular path.
