According to Newton’s law of universal gravitation, which statements are true? As we move to higher altitudes, the force of gravity on us decreases. As we move to higher altitudes, the force of gravity on us increases. As we gain mass, the force of gravity on us decreases. As we gain mass, the force of gravity on us increases. As we move faster, the force of gravity on us increases.
Question
According to Newton’s law of universal gravitation, which statements are true? As we move to higher altitudes, the force of gravity on us decreases. As we move to higher altitudes, the force of gravity on us increases. As we gain mass, the force of gravity on us decreases. As we gain mass, the force of gravity on us increases. As we move faster, the force of gravity on us increases.
Solution
According to Newton’s law of universal gravitation, the following statements are true:
-
As we move to higher altitudes, the force of gravity on us decreases. This is because the force of gravity decreases with the square of the distance from the center of the Earth.
-
As we gain mass, the force of gravity on us increases. This is because the force of gravity is directly proportional to the mass of the object.
-
The speed at which we move does not affect the force of gravity on us. Newton's law of universal gravitation does not include velocity as a factor. Therefore, the statement "As we move faster, the force of gravity on us increases" is not true.
