Centripetal Acceleration Formula:
| From: | To: |
Centripetal acceleration is the acceleration experienced by an object moving in a circular path, directed towards the center of the circle. It is responsible for keeping the object in circular motion rather than moving in a straight line.
The calculator uses the centripetal acceleration formula:
Where:
Explanation: The formula shows that centripetal acceleration increases with the square of velocity and decreases with increasing radius of the circular path.
Details: Centripetal acceleration is crucial in understanding circular motion in physics, engineering applications like roller coasters and centrifuges, and astronomical phenomena like planetary orbits.
Tips: Enter velocity in meters per second (m/s) and radius in meters (m). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the difference between centripetal and centrifugal acceleration?
A: Centripetal acceleration is the actual acceleration towards the center that keeps an object in circular motion, while centrifugal force is a fictitious force that appears to push objects outward in a rotating reference frame.
Q2: Can centripetal acceleration be negative?
A: No, centripetal acceleration is always positive as it represents the magnitude of acceleration towards the center. The direction is always inward, but the value itself is positive.
Q3: What happens to centripetal acceleration if velocity doubles?
A: If velocity doubles, centripetal acceleration increases by a factor of four (since acceleration is proportional to the square of velocity).
Q4: What are real-world applications of centripetal acceleration?
A: Common applications include car turning on curves, satellites orbiting Earth, amusement park rides, centrifuges in laboratories, and electrons orbiting atomic nuclei.
Q5: How is centripetal acceleration related to centripetal force?
A: Centripetal force is the net force causing centripetal acceleration, related by Newton's second law: \( F_c = m \times a_c \), where m is the mass of the object.
