Unit 9 - Motion of Objects

All matter is acted upon by a variety of forces. Motion results when the forces acting upon an object are unbalanced. In this unit we will examine how all objects in the universe move and obey Newton's Laws of Motion and respond to the universal forces of friction and gravity.

Instruction will be a combination of direct instruction and video lessons supplemented with appropriate worksheets.

SPS8: Students will determine relationships among, force, mass, and motion.
a. Calculate velocity and acceleration.
b. Apply Newton's three laws to everyday situations by explaining the following:
  • Inertia
  • Relationships between force, mass, and acceleration
  • Equal and opposite forces
c. Relate falling objects to gravitational force.
d. Explain the difference between mass and weight.

Specific Assignments:

Assignment 1: Watch the video below entitled "Newton's Laws of Motion" which explains the difference between speed, velocity, acceleration and momentum and how they relate to Newton's Laws of Motion. Complete the worksheet entitled "The Motion of Objects" as you go. Pay particular attention to formulas. (Click here to see worksheet)



Assignment 2: Apply what you have learned about the motion of objects so far to complete the following worksheets. The first is entitled Speed, Velocity, Acceleration and Momentum and the second is What Law is it? (Click here to see worksheet on Speed... and click here to see worksheet on Newton's Laws.)
