Centripetal Acceleration Formula:
| From: | To: |
Centripetal acceleration is the acceleration experienced by an object moving in a circular path, directed toward the center of the circle. It's responsible for changing the direction of the velocity vector while keeping the object in circular motion.
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 physics, designing roller coasters and roads, analyzing planetary orbits, and various engineering applications involving rotating systems.
Tips: Enter velocity in meters per second (m/s) and radius in meters (m). Both values must be positive numbers greater than zero.
Q1: What's the difference between centripetal and centrifugal acceleration?
A: Centripetal acceleration is the actual acceleration toward the center that keeps an object in circular motion. Centrifugal force is a fictitious force that appears to push objects outward in a rotating reference frame.
Q2: Does centripetal acceleration change the speed of an object?
A: No, centripetal acceleration only changes the direction of velocity, not its magnitude. The speed remains constant in uniform circular motion.
Q3: What are some real-world examples of centripetal acceleration?
A: Cars turning on curved roads, satellites orbiting planets, electrons orbiting nuclei, and amusement park rides like carousels and roller coasters.
Q4: How does radius affect centripetal acceleration?
A: For a given velocity, centripetal acceleration decreases as radius increases. Larger radius means gentler curvature and less acceleration needed to maintain circular motion.
Q5: What happens if centripetal force is removed?
A: The object will continue moving in a straight line tangent to its circular path at the point where the centripetal force was removed (Newton's first law).
