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 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.
What is the effect of increasing the radius of a circular path on centripetal acceleration (at constant speed)?
Centripetal acceleration decreases.
What happens when a turntable is tilted with a block on it?
The normal force decreases, reducing the maximum static friction force, which in turn reduces the maximum speed the block can have without slipping.
