Motion and Forces
The motion of an object can be described by its position, direction of motion, and speed. A change in motion occurs when a net force is applied.

Objectives:

1. Laws of Motion: Objects change their motion only when a net force is applied. Laws of motion are used to determine (local standard: calculate precisely) the effects of forces on the motion of objects.

Time Range:
1st Quarter; 1.5 weeks

Suggested Teaching Strategies:
CPO Chapter 3 Sections 1 & 3

• Students will define related vocabulary terms; use pre-reading guides to introduce them to the text; and fill in guided outline during class discussion.
• Demonstrate the independence of vertical and horizontal motion using the simultaneous velocities demonstrator.
• Demonstrate the law of conservation of momentum and Newton's third law of motion, using the Astro-blaster and Newtonian demonstrator.
• Demonstrate centripetal forces and acceleration using the gyroscopic bicycle wheel.
• Reinforce student understanding using worksheets and activities.
