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.
What is the difference between inertial and gravitational mass?
Inertial mass measures resistance to acceleration; gravitational mass measures interaction with gravity. They have the same value.
Compare inertial and non-inertial frames of reference.
Inertial frame: object at rest or constant velocity, laws of physics are the same. Non-inertial frame: object accelerating, fictitious forces may be experienced.
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.
