# Circular Motion

Task: Verify the relationship F = mv2 / r at the central circular motion with constant speed.
Do

two different measurements.
Determine v in two different ways in each of the two försöken.Utförande: We determined the speed of the weight that went around in the sling in two different ways,

Speed 1) Took time at 10 yards, and calculated the momentum by taking the route through time.

Speed 2) used Speedometern.

Results: Speed 1 was determined first to take out the stretch as the weight passed through to figure out the circumference (o = r * 2 *).
Then we took the perimeter and divided at the time of a lap (total time by 10 yards) and got out the fly.

Speed 2 on the weight we got out by first figuring out the time on a lap of Formula

(T = (2 ** r) / v), the radius was 0.30 m on the entire sling.
Then we took the time and worked with the same formula out the speed where the weight set.
