Goal 2

The learner will construct an understanding of forces and motion.

Objective 2.02

Investigate and analyze forces as interactions that can change motion:

  • In the absence of a force, an object in motion will remain in motion or an object at rest will remain at rest until acted on by an unbalanced force.
  • Change in motion of an object (acceleration) is directly proportional to the unbalanced outside force and inversely proportional to the mass.
  • Whenever one object exerts a force on another, an equal and opposite force is exerted by the second on the first.

g: a pendulum
Students will time the periods of pendulums to determine if length or mass affects them. Students can then use a pendulum to calculate the acceleration of gravity.
