AP Physics 1 Summer Assignment Dr. Haug

Welcome to AP Physics 1. Please join the Google Classroom with Code p6vmvsl. This ​ ​ summer assignment is posted in the classroom. You can hyperlink to sites from the Doc if it is easier than typing in the URL for the links.

1. Complete the vocabulary on the next page. You are responsible for creating a list of definitions. While we don’t memorize a lot in this class you need to be familiar with the terms used in this class. They should become a part of your everyday language. You will have a vocabulary test on the first Friday of the school year. 2. We will focus many of our lab experiences and problem solving sessions on the force of and the acceleration due to gravity. When you sign up for AP Physics 1, it is assumed that you already have learned about gravity and have more than a basic understanding of gravity. In order to catch up on what you have not necessarily learned before, please do the following: a. Watch the following videos: i. https://www.youtube.com/watch?v=TMVhy_NQm_Y&t=38s This is a ​ Tedx talk given by an astronaut. ii. https://www.youtube.com/watch?v=E43-CfukEgs This video compares ​ the falling of a bowling ball and a feather. iii. https://www.youtube.com/watch?v=7gf6YpdvtE0&t=45s This video from ​ Crash Course explains the Law of Universal Gravitation. iv. https://www.youtube.com/watch?v=rFdbY_V7vIo This video introduces ​ the difference between weight and mass. v. https://www.youtube.com/watch?v=_Z0X0yE8Ioc Veritasium explains ​ the difference between weight and mass. vi. https://www.youtube.com/watch?v=57gKnA94Doc Another explanation ​ of mass vs. weight by Professor Dave. The concept of normal force is also explained. b. Complete the worksheet attached. Answer all questions using complete sentences. If equations or variables are needed be sure to use them correctly.

AP Physics 1 Summer Assignment

As you transition into AP Physics 1, there are terms you must be very familiar with. These terms should be used regularly and correctly to describe motion. Use the internet to define and describe the following terms. I highly suggest that you DO NOT just use the first ​ definition you find. Sometimes these terms can have more than one meaning. Remember you ​ are looking for a physics definition. Include units and equations when necessary. You should define these terms using a Google Doc. You may want to make a table so that you can have a term, a definition, and a unit or equation as needed.

AP Physics 1 Summer Assignment

After watching the videos linked on the first page and reviewing information from Lesson 5 of the physics classroom, https://www.physicsclassroom.com/class/1DKin/Lesson-5/Introduction, ​ ​ answer the following questions. Answer using complete sentences.

1. Define gravity. 2. What variables determine the magnitude of gravity acting between two objects? Be specific. 3. What is the value for the Universal Gravitation constant (G)? Be sure to include proper ​ ​ units. 4. What is the value for acceleration due to gravity on Earth (g)? Be sure to include proper ​ ​ units. 5. If the distance between two objects is tripled, how does the magnitude of the gravitational force change? Explain your reasoning. 6. Explain the conditions necessary for a feather and a bowling ball to reach the ground at the same time when dropped from the same height. 7. Compare and contrast weight and mass. 8. A physics student has a mass of 60kg. What is the weight of that student? Be sure to show all work and use correct units. 9. How do the weight and mass of this physics student on Earth compare to the weight of the student on the moon? Explain your reasoning. 10. When an object falls freely under the influence of gravity there is a net force mg exerted ​ ​ on it by the Earth. Yet by Newton’s 3rd Law the object exerts an equal and opposite force on the Earth. Does the Earth move? Explain. 11. As you saw in one of the videos, when astronauts are in space they seem to “float” through space. Are the astronauts weightless in space? Explain your answer.
