Watch the video that matches the chapter we are in. Answer these questions on
this worksheet and submit your answers on Canvas as a single PDF file. Do not
share your answers with anyone else. I will be comparing responses I receive with
the other two Physics teachers. We will fail all students who cheat on this
assignment, whether you copied or allowed others to do so! Do the right thing!
1) Name of video
Types of Motion - Discovery Education
2) What were three important/significant ideas discussed in the video?
Three important/significant ideas discussed in the video is Hooke's law states that the amount of stretch or
compression is directly proportional to the force applied, Keplar's first law, or the law of elipses states that all
planets move in elliptical orbits with the sun at one focus. An ellipse resembles a stretched out circle. The sun
is not at the center of the ellipse, but at one of its two focal points. The other focal point has no physical
significance for the orbit. Keplar's third law, or the law of periods, states that the square of the period of any
planet is proportional to the cube or the semi-major axis of its orbit.
3) Name three scientists who were interviewed for or mentioned in the
video, and the universities where they work or worked.
Robert Hooke - Proffessor of Geometry at the Gresham College in London.
Sir Issac Newton - University of Cambridge Royal Society Royal Mint.
Johannes Keplar - Eberhard Karls University of Tübingen.
4) What was one fact from the video that was completely new to you?
Kepler's second law, or the equal areas law, states that a line that connects a planet to the sun sweeps out
equal areas in equal times.
5) What was the most interesting idea from the video?
The planet moves slower when away from the sun. So the same area is swept out in a given time as at larger
distances. Time as at larger distances.
