What are the differences between centripetal and tangential acceleration?
Centripetal: Changes direction, not speed (perpendicular to velocity). Tangential: Changes speed, not direction (parallel to velocity).
Compare period and frequency in uniform circular motion.
Period (T): Time for one revolution. Frequency (f): Revolutions per unit time. Relationship: f = 1/T.
What is the process to find the minimum speed to maintain circular motion at the top of a vertical loop?
Set gravity equal to the centripetal force: , then solve for v: .
How do you determine the net acceleration in circular motion when both centripetal and tangential acceleration are present?
Find the vector sum of centripetal and tangential accelerations. The net acceleration is angled relative to the circular path.
Describe the process of analyzing forces on banked curves to determine centripetal force.
Combine static friction and normal forces to determine the net centripetal force. Quantitatively analyze only when friction isn't needed for uniform circular motion.
Describe the process of finding the relationship between period, radius, and mass using Kepler's Third Law.
Use the formula , where T is the orbital period, R is the orbital radius, M is the mass of the central body, and G is the universal gravitational constant.
Describe the steps to solve a conical pendulum problem.
- Draw a free-body diagram. 2. Resolve tension into horizontal and vertical components. 3. Use vertical components to find tension. 4. Use horizontal component as centripetal force to find speed or other variables.
