Formulae

Variables:
  • Mass ("M" in kilograms(kg))
  • Distance ("D" in meters (m)) lifted
  • Time ("t" in seconds (s)) taken

Constant:
  • Gravity ("g" in N/kg)

Calculations:
  • Force (N) = M * g
  • Work (N*m) = M * g * D
  • Power (Watts) = W/t

Instructions

1. Choose variables
  • Hold your the mouse over the variable buttons (Mass, Time, Distance).
  • Select one of the two values by clicking on it.

2. Start the experiment
  • Press the 'Go' button, the mannequin will execute the experiment with the values you selected.

3. Observe the results
  • Observe how the values you selected affect the final values of Force, Work and Power

 

Distance

Effect

The distance a mass is moved is directly proportional to the amount of Work done by moving it.

 

Notes:

In this experiment, the mannequin can only lift the weight to a height of 1.2 meters.

Selecting a distance of 3.6 meters will cause him to lift the mass 3 times, selecting 7.2 meters will cause him to lift the mass 6 times.

 

Time

Effect

The Time it takes to move the mass is inversly proportional to the amount of Power generated by the movement

 

Notes:

Notice the difference in Power generated by changing the time from 12 seconds to 6 seconds

 

Mass

Effect

The Mass of the object being moved is directly proportional to the Force required to move it.

 

Notes:

Choose between a 5kg weight and a 20kg weight.
