Included Quiz Questions
What does the letter “g” stand for in the context of gravity?
- The gravitational acceleration near the surface of the earth
- The universal gravitational constant
- The gravitational force near the surface of the earth
- The gravitational mass in Newton’s law of gravity
- The ratio of the Earth’s mass to its radius
If you double the mass of an object, what will happen to the gravitational force acting on it by earth?
- It doubles.
- It increases by a factor of 4.
- It decreases to one-half.
- It decreases to one-quarter.
- It remains unchanged.
What is the expression for the gravitational constant g and its unit?
- g = GM_E/(R_E)² , [g] = m/s²
- g = G(M_E)²/(R_E)² , [g] = N
- g = GM_E/(R_E) , [g] = m/s²
- g = GM_E/(R_E) , [g] = m/s
- g = M_E/(R_E)² , [g] = m/s²
