About this app
In this free practice you will find a model scale of an elevator structure, in which you can modify the gravity parameters for each environment (the Moon, Earth and Mars), the height of the cabin and its mass. The goal of this lab is to apply Newton's second law to find the mass of the counterweight and cause the cabin to rise with a desired acceleration.
