Competency Goal 6: The learner will conduct investigations, use models, simulations, and appropriate technologies and information systems to build an understanding of motion and forces.

Objectives

6.01 Demonstrate ways that simple machines can change force.

6.02 Analyze simple machines for mechanical advantage and efficiency.

6.03 Evaluate motion in terms of Newton's Laws:

• The force of friction retards motion.
• For every action there is an equal and opposite reaction.
• The greater the force, the greater the change in motion.
• An object's motion is the result of the combined effect of all forces acting on the object.
• A moving object that is not subjected to a force will continue to move at a constant speed in a straight line
• An object at rest will remain at rest.

6.04 Analyze that an object's motion is always judged relative to some other object or point.

6.05 Describe and measure quantities that characterize moving objects and their interactions within a system:

• Time.
• Distance.
• Mass.
• Force.
• Velocity.
• Center of mass.
• Acceleration.

6.06 Investigate and analyze the real world interactions of balanced and unbalanced forces:

• Sports and recreation.
• Transportation.
• The human body.
