Unit 4: Newton's Laws of Motion



Newton's Laws of Motion DUE DATE: ___________________

Unit Objectives: By the end of this unit, you should be able to:

➢ Distinguish between and explain each of Newton's three laws of motion.

➢ Calculate net force on an object.

➢ Identify action and reaction.

➢ Describe the difference between mass and weight.

Vocabulary Terms

|Equilibrium |Force |Friction |Inertia |Mass |

|Newton's First Law |Net force |Newton (N) |Normal force |Support force |

|Weight |Inversely |Newton's Second Law |Pressure |Terminal Speed |

|Terminal Velocity |Action Force |Reaction Force |Interaction |Newton's Third law |

Complete one "layer" before going on to another layer. No more than two assignments will be checked of, by your teacher, on any one day, in any layer. Each assignment has a point value based on the amount of time and effort necessary to complete that task. You must earn the required number of points in any one layer before moving to the next layer. If you finish a layer, you must move onto the next layer.

Be prepared to discuss and answer questions about each of your assignments. Failure to do so will result in no credit for that assignment. When appropriate, you may work with a partner or partners, but you must be able to answer the teacher's questions without any assistance.

All assignments must be stamped by the due date. No late assignments will be accepted.

EXTRA INFORMATION:

Forces

1. Know that there are four fundamental forces in nature: gravitation, electromagnetism, weak nuclear force, and strong nuclear force.

2. Know that every object exerts gravitational force on every other object, and how this force depends on the masses of the objects and the distance between them.

3. Know that materials containing equal amounts of positive and negative charges are electrically neutral, but that a small excess or deficit of negative charges produces significant electrical forces.

4. Understand the relationship between force and pressure, and how the pressure of a volume of gas depends on the temperature and the amount of gas.

5. Explain how electric currents cause magnetism and how changing magnetic fields produce electricity (e.g., electric motors, generators).

6. Represent the magnitude and direction of forces by vector diagrams.

7. Know that when one object exerts a force on a second object, the second object exerts a force of equal magnitude and in the opposite direction on the first object (i.e., Newton’s Third Law).

Motion

8. Apply Newton’s Laws to describe and analyze the behavior of moving objects, including:

• displacement, velocity, and acceleration of a moving object

• Newton’s Second Law, F = ma (e.g., momentum and its conservation, the motion of an object falling under gravity, the independence of a falling object’s motion on mass)

• circular motion and centripetal force.

9. Describe relative motion using frames of reference.
