Understanding Uniform Circular Motion
Uniform circular motion occurs when an object moves along a circular path with a constant speed. Although the speed remains constant, the velocity vector changes direction continuously, resulting in an acceleration directed towards the center of the circle, known as centripetal acceleration. This acceleration is responsible for changing the direction of the velocity, keeping the object moving in a circle.
The centripetal force is the net force required to keep the object moving in this circular path. It always points towards the center of the circle and is calculated based on the mass of the object, its velocity, and the radius of the circle. This calculator helps you find the centripetal force, acceleration, velocity, or period by inputting known values.
You can provide either the velocity or the period of the motion along with the mass and radius. The calculator will compute the missing values using the fundamental physics formulas governing uniform circular motion. This tool is ideal for students, educators, and enthusiasts seeking precise and educational calculations.
Formula & Variables
Centripetal Force: F = m × a = m × (v² / r) Velocity (if period known): v = (2 × π × r) / T Variables: m = mass of the object (kg) r = radius of circular path (m) v = velocity (m/s) T = period (s) a = centripetal acceleration (m/s²) F = centripetal force (N)
Frequently Asked Questions
What is uniform circular motion?
Uniform circular motion describes the movement of an object traveling at a constant speed along a circular path. Although the speed is constant, the velocity vector changes direction continuously, resulting in acceleration towards the center of the circle called centripetal acceleration.
How is centripetal force calculated?
Centripetal force is the net force causing the inward acceleration of an object moving in a circle. It is calculated using the formula F = m × v² / r, where m is mass, v is velocity, and r is the radius of the circular path.
Can I calculate velocity if I know the period?
Yes. Velocity can be calculated from the period (T) using the formula v = 2πr / T, where r is the radius of the circular path. This calculator automatically computes velocity if you provide the period instead of velocity.
