Lesson 8: Newton's Laws of Motion

Overview:

In this activity, you will review Newton's three Laws of Motion in preparation for solving more complex dynamics problems. After reviewing the three laws, you will complete a quiz and participate in a discussion based on the three laws.

Curriculum Expectations:

Overall Expectations:
B2. Investigate, in qualitative and quantitative terms, forces involved in uniform circular motion and
motion in a plane, and solve related problems.

B3. Demonstrate an understanding of the forces involved in uniform circular motion and motion in a plane.

Specific Expectations:
B2.1 Use appropriate terminology related to dynamics, including, but not limited to: inertial and non-inertial frames of reference, components,  centripetal, period, frequency, static friction, and kinetic friction.

B2.3 Analyse, in qualitative and quantitative terms, the relationships between the force of gravity, normal force, applied force, force of friction, coefficient of static friction, and coefficient of kinetic friction, and solve related two-dimensional problems using free-body diagrams, vector components, and algebraic equations (e.g., calculate the acceleration of a block sliding along an inclined plane or the force acting on a vehicle navigating a curve).

B2.5 Analyse, in qualitative and quantitative terms, the relationships between the motion of a system and the forces involved (e.g., a block and algebraic equations to solve related problems sliding on an inclined plane, acceleration of a pulley system), and use free-body diagrams and algebraic equations to solve related problems.

Success Criteria:

  1. State Newton's 1st law of motion and give an example that helps to explain it in everyday life.
  2. Is a net force required for an object to maintain a constant velocity?
  3. What is required to change the velocity of an object in magnitude, direction, or both?
  4. Do internal forces have an effect of an object's motion? What if instead it is an external force?
  5. Describe inertia.
  6. What is an object's mass, and how is an object's mass related to its inertia?
  7. State Newton's 2nd law of motion and give an example that helps to explain it in everyday life.
  8. How can you determine the direction of acceleration?
  9. What are the SI units for forces?
  10. State Newton's 3rd law of motion and give an example that helps to explain it in everyday life. 
  11. According to Newton's 3rd law, do the two equal and opposite forces must always act on different objects?
  12. Is weight equivalent to the gravitational force?
  13. Is the normal force the reaction force to gravity? 
  14. Is the normal force always equal in magnitude to the force of gravity. Provide two examples to justify your reasoning.

Time Allocation: 1 hour


Learning Activities:

Read pages 70 - 75 from Nelson 2.2

In the playlist below, video:
  1. Will explain Newton's 1st Law of motion.
  2. Will show you how to calculate the force needed to keep an object from accelerating using Newton's First Law of motion.
  3. Will explain Newton's 2nd Law of motion.
  4. Will show you how to calculate the acceleration of a 5kg object sliding down a wedge.
  5. Will explain Newton's 3rd Law of motion.
  6. Will show you how to calculate the mass needed to keep a car from sliding down a wedge using Newton's 3rd Law of motion.
  7. Will show you how to calculate the tension of a rope using Newton's 3rd Law of motion.

Practice question 2 on page 73.
Practice questions 1, 2, and 3 on page 74.

Task:

Solve questions 4, and 6 from Nelson 2.2 Review on page 76.

Optional Extension: 
  • Solve questions 3, 8, and 9 on page 76.

Reflect:

What did you find different from your preconceptions and intuitive understanding of the motion of objects? Which concept did you find most difficult to understand? Why was it difficult, and what helped clarify it?

Additional Resources:

Will explain the tension of the previous video using Newton's 3rd Law of motion.
