What are the steps to analyze circular motion with FBDs?
- Draw a Free-Body Diagram (FBD). 2. Choose a coordinate system with the positive direction towards the center of the circle. 3. Identify all forces acting on the object and break them into components if necessary. 4. Apply Newton's second law.
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 are the key differences between inertial and gravitational mass?
Inertial Mass: Measures resistance to acceleration. Gravitational Mass: Measures interaction with gravity. They have the same value.
Differentiate between inertial and non-inertial frames of reference.
Inertial Frame: Object is at rest or moving at constant velocity; laws of physics are the same for all observers. Non-Inertial Frame: Object is accelerating; fictitious forces may be experienced.
