The mass, hanging over the pulley, is representative of the centrifugal force acting on the three-hooked mass while it is rotating. What is the justification for why we able to use this value of centrifugal force for that of the centripetal force during the experiment?2. Identify the independent variable(s) in this experiment.3. Identify the fixed variable(s) in this experiment.4. Identify the dependent variable(s) in this experiment.

1) We are using centrifugal force because of its direction since direction is away from pulley hence it is centrifugal force.

2) Independent variable:Mass

3)  Fixed Variable:Spring constant

4) Dependent variable:Centrifugal force.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

force tends to be low and long diustance masses are high
