Introduction to circular motion

Circular motion

---

This simulation shows what circular motion looks like. Observe the relationship between period, radius and linear velocity.

Change of velocity in circular motion

---

This animation shows the change of the velocity vector in a circular motion. Click on the boxes of the different steps (1, 2...) and observe the results.

Centripetal acceleration

---

This animation shows the velocity and acceleration vectors in a circular motion.

Car in a circular motion

---

When a car moves in a circular motion, centripetal force is generated by friction with the surface. On a wet surface, the friction is reduced, the car will tend to move outwards.
