Center of Gravity
About the Lecture
The lecture Center of Gravity by Jared Rovny, PhD is from the course Equilibrium.
Included Quiz Questions
How are the center of gravity and center of mass related?
- They are the same if each object experiences the same gravitational acceleration
- They are always the same
- They are always different
- They are the same if all the objects are experiencing force according to Newton’s law of gravity
- They always have different units
Many objects with equal mass are symmetrically distributed around the origin (x = 0), what is the location of center of mass and center of gravity if the masses are near the surface of the Earth?
- The center of mass and the center of gravity will be at x = 0
- The center of mass will be at x = 0, but the center of gravity will depend on the specific location of masses
- The center of gravity will be at x = 0, but the center of mass will depend on the specific location of masses
- The center of mass and the center of gravity will depend on the specific location of masses
- The center of mass and the center of gravity will depend on the mass of each object and their locations
An object with mass m₁ is located at x₁ = 2 m. Where should a second object of mass m₂ = 2m₁ be located such that the center of gravity of the whole system would be at the origin x = 0?
- x₂ = -1 m
- x₂ = -2 m
- x₂ = 4 m
- x₂ = 1 m
- x₂ = 0

All the masses are added up of objects, divided by it!!!
