Conservations of Momentum and Energy - Columbia Southern University

Learning Outcomes - Conservations of Momentum and Energy

1. Explain Newton's laws of motion at work in common phenomena.

Relate impulse-momentum theorem to Newton's second law.

Discuss the relationship between linear momentum conservation and Newton's third law.

2. Explain the concepts and applications of momentum, work, mechanical energy, and general relativity.

Show examples of momentum conservation in various physical activities.

Distinguish between kinetic and potential energy.

Correlate the relation among work, energy, and power in daily life.

Learning Activities
Nongraded Learning Activities are provided to aid students in their course of study. You do not have to submit them. If you have questions, contact your instructor for further guidance and information.

To practice what you have learned in this unit, complete the following problems and questions from the textbook. The answers to each problem can be found in the "Odd-numbered Answers" section in the back of the textbook. The question number from the textbook is indicated in parentheses after each question.

Question 1. Railroad car A rolls at a certain speed and makes a perfectly elastic collision with car B of the same mass. After the collision, car A is observed to be at rest. How does the speed of car B compare with the initial speed of car A?

Question 2. When you jump from a significant height, why is it advantageous to land with your knees slightly bent?

Question 3. Compared with a car moving at some original speed, how much work must the brakes of a car supply to stop a car that is moving twice as fast? How will the stopping distances compare?

Question 4. What is the efficiency of a machine that miraculously converts all the input energy to useful output energy?

Question 5. This question is typical on some driver's license exams: A car that was moving at 50 km/h skids 15m with locked brakes. How far will the car skid with locked brakes if it was moving at 150 km/h?

Question 6. On a playground slide, a child has potential energy that decreases by 1000 J while her kinetic energy increases by 900 J. What other form of energy is involved, and how much?

Question 7. If a trapeze artist rotates once each second while sailing through the air and contracts to reduce her rotational inertia to one-third of what it was, how many rotations per second will result?

Question 8. Dan and Sue cycle at the same speed. The tires on Dan's bike are larger in diameter than those on Sue's bike. Which wheels, if either, have the greater rotational speed?

Question 9. You sit at the middle of a large turntable at an amusement park as it is set spinning and then allowed to spin freely. When you crawl toward the edge of the turntable, does the rate of the rotation increase, decrease, or remain unchanged? What physics principle supports your answer?

Question:

Find and select images that apply/explain/identify various physical concepts that we have learned in this unit (study guide from unit attached).

Identify the concept that is being demonstrated in that image, and provide an explanation that relates the image to the concept. Your presentation must contain at least these concepts:

How impulse-momentum theorem relates to Newton's second law.

The relationship between linear momentum conservation and Newton's third law.

How momentum conservation is exemplified in various physical activities.

The difference between kinetic and potential energy.

The relation among work, energy and power in daily life.

Some other topics that may be included are impulse, elastic/inelastic collision, energy conservation, power, work, angular momentum conservation, torque, center of mass/gravity, and centripetal/centrifugal force, among others.

Your PowerPoint must be a minimum of 10 slides not including the title and reference slide. You are required to insert appropriate images and diagrams to enhance your content. In addition to the images, you must use at least two scholarly references in your presentation. Any images or information used should be cited in APA format. Also, it is a good idea to utilize presenter notes and provide narration, but this is not required.
