All Flashcards
Outline the steps for analyzing circular motion with a free-body diagram.
- Draw FBD. 2. Choose coordinate system with positive direction towards the circle's center. 3. Identify and resolve forces into components. 4. Apply Newton's second law.
What is a vector field?
A map showing the magnitude and direction of a quantity at different points in space.
Define uniform circular motion.
Movement in a circle at a constant speed.
What is centripetal force?
The net force that keeps an object moving in a circular path, directed towards the center of the circle.
Define gravitational force.
The force of attraction between objects with mass.
What is inertial mass?
A measure of an object's resistance to acceleration.
What is gravitational mass?
A measure of how strongly an object interacts with gravity.
What is the effect of doubling the radius of a satellite's orbit on the gravitational force?
The gravitational force is reduced to one-fourth of its original value.
What is the effect of tilting a turntable on the maximum speed a block can have without slipping?
The maximum speed decreases because the normal force is reduced, which reduces the maximum static friction force available to provide the centripetal force.
