When drawing free-body diagrams, does the label “centripetal force” get used? Explain why or why not.
Gravitational Forces (A) Gravitational, Electrical, Magnetic, and Nuclear Forces Math Connections Name: Date: Gravitational Forces Gravitational force is one of the four fundamental forces of nature. It is always attractive and acts between all particles of matter. Law of Universal Gravitation This law states that any two objects with mass exert a gravitational force on each other. The force has the same magnitude on each object. The magnitude is directly proportional to the product of the objects' masses. It is inversely proportional to the square of the distance between the objects. тт, Where, = G(! d' F. = gravitational force between two objects G= gravitational constant = 6.673 × 10-11 N x m²/kg? m, and m, = masses of the two objects in kg d = distance between the two objects in m 1. Calculate the gravitational force between two 100 kg objects located 10 m from one another. F = 6.673×10"| (100)(100) 10? N (100)(200) 10² F = 6.673×10-" N 2.

A satellite in orbit around the earth is at an altitude of 107 percent of the earth's radius. Rounding off our old friend "g" to ten meters per second squared, what is the acceleration due to earth's gravity at the satellite? Your answer should be in meters per second squared, but do not put the unit, just the number.
A parachuter of mass 139 kg above Earth (g = 10 m/s2) experiences a drag force modeled by -0.04 v (N). If the parachuter is released from rest, how fast, in m/s, will the jumper be falling after 1,027 s? (Assume the parachuter doesn't reach the ground in this amount of time.)(I want the speed.) (Please answer to the fourth decimal place - i.e 14.3225)

A 25 kg man floats in space near a planet with a mass of 100 billion kg. The planet’s gravitational force pulls on the man with a force of 0.01 N. Roughly how far is the man from the planet?
Keplers third law may be obtained from the gravitational force law equated to Newtons 2nd law and replacing the acceleraion by that of a centripetal type. The speed may then replaced by the circumference over the period. We ovatain the ratio of (distance)3 and (Period)2 How does this method outlined above express or represent keplers third law? The escape velocity may be obtained by converting all the gravitational potential energy to kinetic energy. This is a factor of sqrt(2) larger than the orbital speed. Was the approach valid? Justify the obtained relationship.

A satellite in orbit around the earth is at an altitude of 137.7 percent of the earth's radius. Rounding off our old friend "g" to ten meters per second squared, what is the acceleration due to earth's gravity at the satellite? Your answer should be in meters per second squared
newtons first law states that objects with more mass have stronger tendencies to maintain their original motion. Yet our centripetal force equation suggests that all masses will maintain a steady orbit provided that their tangenitial speed, v, is the correct match for their orbital radius, r. Provide a physical argument that explains why objects with larger inertias (masses) do not fly off. Is there something that counters this increase in inertia?
