A Fall on the Moon. You and your team are stationed at an earth-based mission control facility and have been tasked with assisting astronauts via radio communication as they exit a spacecraft that has recently landed on the moon. The astronauts intended to explore the lunar surface but, unfortunately, they hit a snag even before they opened the hatch. Their craft has landed right on the edge of a 15-ft cliff, so that there is no way off the lander except to drop that distance from the bottom rung of a ladder on the side of the ship. You look up the structural parameters of the space suits, the gear they are wearing, and the physical limitations of the crew, and find that, on earth, the maximum drop they can safely endure is 4.0 ft. (a) Is it safe for them to make the 15-ft drop on the moon? (b) What is the maximum drop they can safely endure on the moon? Note that the acceleration due to gravity on the moon is one-sixth as large as that on earth.

Gravitational force

In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.

Acceleration Due to Gravity

In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.

A Fall on the Moon. You and your team are stationed at an earth-based mission control facility and have been tasked with assisting
astronauts via radio communication as they exit a spacecraft that has recently landed on the moon. The astronauts intended to explore
the lunar surface but, unfortunately, they hit a snag even before they opened the hatch. Their craft has landed right on the edge of a
15-ft cliff, so that there is no way off the lander except to drop that distance from the bottom rung of a ladder on the side of the ship.
You look up the structural parameters of the space suits, the gear they are wearing, and the physical limitations of the crew, and find
that, on earth, the maximum drop they can safely endure is 4.0 ft. (a) Is it safe for them to make the 15-ft drop on the moon? (b) What is
the maximum drop they can safely endure on the moon? Note that the acceleration due to gravity on the moon is one-sixth as large as
that on earth.

Martin was standing on a very high cliff on the moon (where there is no atmosphere). He had a rock and a feather in his hand. He let them go at the same time. Select all the statements that are true. The rock hit the ground first. The feather hit the ground first. The rock and the feather hit the ground at the same time. Both the rock and the feather were traveling faster when they landed than when Martin let them go. It took the rock more time to hit the ground than if it had been let go from a cliff of the same height on Mars.

You are standing on a bathroom scale in an elevator (yes people are staring at you). You weigh 50 kg but the scale reads in Newtons. Weight (force of Gravity) = Mass x Gravity (10m/s2) As the elevator comes up on the ground floor it decelerates at 2 m/s2 downward. What is the Gravitational Force? Since the elevator is decelerating downward does the Normal Force have to be greater than, equal to or less than the Force of Gravity? Are the forces balanced or unbalanced? Draw a free body diagram of the forces acting on you. Be sure to draw the size of your arrows appropriately. What is the Net Force, using Newton’s 2nd Law, while the elevator is decelerating downward? What is the Normal Force? What does the scale read as the elevator is decelerating downward? What pattern did you notice occurred between all of the different scenarios?

A planet has 2 moons which are on opposite sides of the planet. The gravity force from the 2 moons cancels out, producing zero net force on the planet. Moon #2 has a mass which is 3.67 times larger than Moon #1. Moon #2 is times farther away from the planet than Moon #1 is.
You encounter a strange cosmic string in outer space. The string extends along the x axis from x = 0 m to x = 4.6 x 104 m. You are located at x = -5.4 x 104 m. You experience a gravitational field equal to 9.6 x 10-6 N/kg at this location. Assuming the string has a constant linear mass density, calculate this linear mass density, in units of 105kg/m. Use G = 6.7 x 10-11 N m2/ kg2. (Please answer to the fourth decimal place - i.e 14.3225)
