2. In this experiment,what random error is involved and how it will affect the experiment result? CENTRIPETAL ACCELERATION OBJECTIVE To calculate the net force on an object moving in uniform circular motion and compare with the expected value. THEORY A. Mass Rotating in Uniform Circular Motion Consider the Centripetal Force Apparatus below. The mass M is rotating in uniform circular motion about the vertical rod in a radius R. adjustment leveling Diagram Applying Newton's 2 Law in the radial direction gives a net force in the radial direction given by F. MAawa, where a, The speed of the mass M is given 4A R and thus a Therefore, M

Explanation / Answer

Systematic error in the system is most probably due to friction.

The random error possibly due to human error in counting number of rotation.

The other two possible source of error is time measurement and radius measurement.

Time error can be reduced by not taking long time for revolution and also taking small radius.
