PHYS 2 Chapter Notes - Chapter 13.1 - 13.4: Inertial Frame Of Reference, Gravitational Constant, Apparent Weight
Document Summary
Apparent weight of a body on earth differs slightly from the earth"s gravitational force. Weight = the total gravitational force exerted on the body by all other bodies in the universe. When body is near the surface of the earth, we can ignore all other gravitational forces is the radius of the earth: is the mass of the earth. Acceleration due to gravity is independent of the mass of the body. Consider a body of mass outside the earth. Compute the work done by the gravitational force when the body moves directly away from/toward the center of the earth, from to. Is the radial component of the gravitational force. Have chosen to be zero when the body of mass is infinitely far from earth. Component in the direction outward from center of earth. Gravitational constant (g) = a physical constant that has the same value for any two particles.
