Circular Motion

Circular motion is motion along a circular path. In uniform circular motion, speed remains constant but velocity changes because direction changes at every instant. Instantaneous velocity is tangent to the circular path and the radius vector joins centre to particle.

Uniform circular motion: speed constant, velocity variable.
Non-uniform circular motion: speed and direction both may change.
Acceleration is toward centre even when speed is constant.

Common mistakes: Thinking acceleration is zero because speed is constant, confusing speed with velocity, taking centripetal acceleration tangentially, and forgetting acceleration is toward centre.

Angular Displacement

Angular displacement measures rotation of the radius vector. It must be used in radians in standard formulas.

s = rθθ = s/r1 revolution = 2π rad180° = π rad

Angular Velocity

Angular velocity is rate of angular displacement. Its direction is given by right-hand rule.

ω = θ/tv = rωω = 2π/Tω = 2πf

Linear Quantity

Displacement, velocity, acceleration

Angular Quantity

Angular displacement, angular velocity, angular acceleration

Connection

Linear speed = radius × angular speed.

Angular Acceleration

Angular acceleration is rate of change of angular velocity. Uniform circular motion has zero angular acceleration; non-uniform circular motion has angular acceleration.

α = Δω/Δta_t = rα

Centripetal Acceleration

Centripetal acceleration is directed toward centre and is caused by change in direction of velocity.

a_c = v²/ra_c = rω²a_c = vω

For two nearby points on a circle, velocity vectors have same magnitude but different directions.

The change in velocity points approximately toward centre for small time interval.

Taking the limit gives a_c = v²/r = rω².

Centripetal Force Basic Intro

Centripetal force is the net inward force required for circular motion. It is not a new kind of force; tension, friction, gravity, normal reaction or electric force can provide it.

F_c = mv²/rF_c = mrω²

Examples: stone tied to string, car turning on road, satellite around Earth, electron around nucleus and banked road basic idea.

Radius of Curvature

Radius of curvature is the radius of the instantaneous circle that best matches a curved path at a point. It connects general curved motion to circular motion.

a_n = v²/RR = v²/a_n

Tangential and Centripetal Acceleration

Whenever a particle moves on a curved path, two independent accelerations may exist: normal/centripetal acceleration changing direction of velocity, and tangential acceleration changing speed.

Centripetal Acceleration

Direction is toward centre of curvature. It changes direction of velocity, does not change speed, is always normal to velocity, and is called normal acceleration.

a_c = v²/ra_c = rω²

Tangential Acceleration

Tangential acceleration acts along tangent and changes magnitude of velocity. It may increase speed or decrease speed.

a_t = dv/dta_t = rα

Resultant Acceleration

When both accelerations exist simultaneously, they are perpendicular.

a = √(a_c² + a_t²)tan θ = a_t/a_ctan θ = (dv/dt)/(v²/r)

Uniform Circular Motion

a_t = 0. Only centripetal acceleration exists.

Speed Increasing

a_c ≠ 0 and a_t > 0. Resultant tilts forward from centre direction.

Speed Decreasing

a_c ≠ 0 and a_t < 0. Resultant tilts backward from centre direction.

Centripetal acceleration changes direction, not speed.

Tangential vs Direction

Tangential acceleration changes speed, not the normal direction of velocity.

Total Acceleration

When speed changes, use resultant acceleration, not only v²/r.

Normal vs Tangential

Normal acceleration points toward centre; tangential acceleration lies along tangent.

Radians

Radians must be used in angular formulas.

Force Misconception

Centripetal force is the inward net force, not a separate physical force.
