Circular Motion Calculator

Find linear speed and centripetal acceleration for circular motion.

Linear speed 8
Centripetal acceleration (m/s²) 32

Formula: v = ω·r ; a = ω²·r

Step-by-step with your numbers:
1. Values used:
2. Angular velocity = 4 rad/s
3. Radius = 2
4.
5. Linear speed = Angular velocity x Radius = 4 x 2 = 8
6. Centripetal acceleration = 32m/s²
Did we solve your problem today?

Relate the spin rate of circular motion to the linear speed and inward acceleration.

The math behind it

Linear speed v = ω·r. Centripetal acceleration a = ω²·r = v²/r points toward the center.

Worked example

ω = 4 rad/s, r = 2 m → speed 8 m/s, acceleration 32 m/s².

FAQ

Why is there acceleration at constant speed?

The direction keeps changing, which is itself an acceleration.
