Physics+20-+CircularMotion-1-1

Explain circular motion, using Newton’s laws of motion 1. Describe uniform circular motion as a special case of two-dimensional motion. 2. Explain, qualitatively and quantitatively, that the acceleration in uniform circular motion is directed toward the centre of a circle. 3. Explain, quantitatively, the relationships among speed, frequency, period and radius for circular motion. 4. Explain, qualitatively, uniform circular motion in terms of Newton’s laws of motion. 5. Explain, quantitatively, planetary and natural and artificial satellite motion, using circular motion to approximate elliptical orbits predict the mass of a celestial body from the orbital data of a satellite in uniform circular motion around the celestial body. 6. Explain, qualitatively, how Kepler’s laws were used in the development of Newton’s law of universal gravitation.

1. Find a resource that explains circular motion, and acceleration in uniform accelerated motion. http://mathworld.wolfram.com/UniformCircularMotion.html

2. Explain how to swing the bowling ball around in a full circle when it is positioned vertically.

3. Complete the following assignment. When finished, take screen shots of assignment and post. http://dev.physicslab.org/Document.aspx?doctype=5&filename=CircularMotion_UniformCircularMotion.xml

4. Discuss what conditions you imposed on the following two simulations, and explain what happened. Did the masses behave as you predicted they would? Explain the differences between the two apps.

5. What are the meaning of the arrows, what happens to the arrows as you increase the velocity?

6. Satellites go up, and for the most part they stay in orbit around the earth. What do we need to know before we launch a satellite in space? How does the information relate?

7. Take a screen shot of the following assignment and load it onto your own Google maps page. http://dev.physicslab.org/Document.aspx?doctype=5&filename=UniversalGravitation_Satellites.xml
