1. In an experiment to discover the effect of centripetal force on velocity, an object of mass m was swung on the end of a string in a horizontal circular path of radius r. F = mv²ir [Equation 1] F = mv³lr The string tension providod the centripatal force F that produced the centripetal accoleration and kept the object revolving in its circular path. The centripetal force was determined by using a spring scale or force sensor that measured the tension on the string By timing the revolutions and calculating the distance traveled by the object, the velocity v of the object was determined.

Question
1. In an experiment to discover the effect of centripetal force on velocity, an object of mass m was swung on
the end of a string in a horizontal circular path of radius r.
F = mv²ir [Equation 1]
F = mv/r
The string tension provided the centripetal force Fthat produced the centripetal acceleration and kept the
object revolving in its circular path.
The centripetal force was determined by using a spring scale or force sensor that measured the tension on the
string.
By timing the revolutions and calculating the distance traveled by the object, the velocity v of the object was
determined.
