Why is the weight of an object on the moon

One day humans will have a permanent presence on the move around there? In preparation for our Let me note that this analysis is inspired by Artemis. I'm not going to spoil the plot except to say there is a girl that moves around on the moon. Weir does a pretty nice job describing what would be different about moving on the moon as compared to the Earth. What is different about the moon compared to the Earth? The biggest difference is the gravitational field on the surface. On the Earth, the field has a strength of 9.8 Newtons per kilogram (we use the symbol g for this). This means that a free falling object (no air resistance) would have a downward acceleration of 9.8 m/s 2. On the moon, There is another important difference with the moon: It doesn't have any air. If you are a human jumping, that might not be a big deal; an Earth-bound jumping human doesn't move fast enough for air resistance to play a significant role. However, on the moon that same human would probably want to wear a spacesuit. This suit would both increase the effective mass and decrease the range of motion for a moving human. Oh, if there is a moon base there would probably be air inside of it so that you wouldn't have to wear a spacesuit unless you just thought it looked cool (it would). Jumping on the moon I will start with the easiest motion—jumping straight up. Let's say that during a normal human jump, a human pushes on the ground with some maximum force over some set distance. This distance is f...

Solution Let the mass of a given object be M. It weight on earth i.e. the force with which the earth attracts this mass is given by W e = G . M e × m R 2 …………1 Where Me is the mass of earth Re is its radius and G is the universal gravitational constant. Its vlue of 6.67 × 10 − 11 N m 2 / k g 2. When that object is taken on the moon its weight ( W m ) will be given by W m = G . M m × m R 2 m Where M m is the mass and R m is the radius of the moon Dividing 2 by 1 we get W m W e = M m M e × ( R e R m ) 2 Now the mass of the earth is about 100 times the mass of the moon and its radius is 4 times that of the moon. ∴ W m W e = 1 100 × ( 4 ) 2 = 16 100 = 1 6 or W m = W e 6 Hence the weight of the object on the moon is about one sixth of its weight on earth. It should be noted that mass of the object on the moon is the same as on the earth.

Teacher’s Guide Intro If someone drops two objects from the same height, one heavy, one light, which one will hit the ground first? If you are like most people, you may instinctively pick the heavier object. And why wouldn’t you? After all, rocks fall faster than feathers. There are other factors besides weight that affect the speed of an object as it falls. This experiment will help students explore those factors, such as gravity and air. Students will use both their eyes and their ears to figure out how mass affects the speed at which something falls. For more information and ideas on how to implement the activity in your classroom check out the Key Terms Mass: A measure of the amount of stuff (or matter) an object has. Not to be confused with weight or volume. Mass only says how much actual stuff there is, not how big an object is or how hard something is pulling on it. Weight: Mass (amount of stuff) times how hard the planet is pulling on it (gravity). This means that your weight on the moon will be 1/6 of that on Earth (gravity on the moon is 0.166 times of that on Earth). However, your mass will still be the same. Force: The push or pull an object feels because of interactions with other objects. If the interaction stops, then there is no force. It is formally defined as mass times acceleration. For example, gravity is a force that represents the pull the Earth has on all objects. Velocity: A measure of how fast something is going in some specific direction. Not to b...

The reasoning for AndrewM's absolutely correct answer is this: Terminal speed means that this speed no longer changes. In other words there is no accelleration happening. This means there is no net force acting on the diver. This means that all forces on the diver have to balance each other. There are only two relevant forces: friction and gravitational pull. Hello Victoria, Nope, it would fall to the surface. In fact, if you dropped a brick and a balloon at the same time they would strike the surface of the moon at the same time! The question we need to ask is why does the helium balloon float here on earth. It has to do with density. For a given amount of space, like inside the balloon, the helium gas weighs less. The helium is "lighter than air" and so the balloon rises. It will continue to rise until the balloon bursts or the helium plus weight of balloon equals weight of equivalent volume of air. Recall that the atmosphere thins as we go up. If it helps think of the helium balloon that same way as bubbles in water. Both will rise because they are lighter than the fluid they displaced. Finally we can answer your original question. Since there is no air on the moon the helium has not displaced anything. Because we are in a vacuum everything falls at the same rate. Sorry for the long answer - please leave a comment if I can help. Regards, APD it depends entirely on the direction you fired the gun. if you fired it perpendicular to the surface, and the bullet had enough ve...

Weight, mass and gravity The weight of an object is the force on it due to the gravitational pull of gravity at that point. Since it is a force, weight is measured in Newtons (not kilograms). Gravity is different on different planets, so the weight of an object on different planets (or moons) is different from its weight on Earth. The mass of an object is the amount of matter that makes up the object and is measured in kilograms. The mass of an object remains the same no matter where the object is in the universe. Gravitational field strength The gravitational field strength ( \(g\) ) of a planet is the weight per unit mass of an object on that planet. It has the units, newtons per kilogram, \(N kg^\) Reveal answer
