In this PhysicsQuest you will learn about what happens when something moves in a circle.
- Answer all of the questions on a piece of paper using the links provided. If a link isn’t working, then find another website that can answer the question.
- All answers must be in your own words. Do not just copy and paste to your paper!
- What does the phrase Uniform Circular Motion suggest? Give an example other than the car example used in the web site.
- Average speed is calculated by dividing distance by time. How is the speed of an object moving in uniform circular motion calculated?
- This semester we have used “t” to represent time in equations. What does “T” represent? Explain what T signifies.
- Do objects moving in uniform circular motion have constant speed? Constant velocity? Explain.
- Is an object moving in uniform circular motion accelerating? Explain.
- Objects moving in circles at a constant speed accelerate towards the ___________ of the circle.
- Draw the direction of the velocity vector when the object is located at point B on the circle.
- Draw the direction of the velocity vector when the object is located at point C on the circle.
Section 2: Acceleration
- Draw the direction of the acceleration vector when the object is located at point C on the circle.
- Draw the direction of the acceleration vector when the object is located at point A on the circle.
Section 3: Centripetal Force
- What is centripetal force? What does the term centripetal mean?
- Why, when sitting as a passenger in a car that is making a circle (turn) to the left do you feel as if there is an outward acceleration or force when there really is an inward acceleration?
