Determining the initial velocity of
A horizontally projected metal sphere
Purpose:
Our main purpose is to determine the initial velocity of a horizontally projected metal sphere.
Equipment:
1234-
Introduction:
A conical pendulum is a pendulum that is spun around in a circle instead of swinging backwards
and forwards, such as like a traditional pendulum. In this experiment a mass is attached to a
circle and made to spin in a circle of a fixed radiu
