Is the force of gravity a push or pull force?
Force of gravity is a pull force. Earth has this force. The earth pulls us towards its center so that we are standing on it. If it was to push we would be in space now.
If earth pulls on a puppy with a force of 2 newtons what amount of force does the puppy exert on earth?
Two newtons is the puppy is just standing there. If the force were more, the puppy would be jumping into the air.
Does the weight of something change depending on where it is?
Yes, because if you are 90 pounds on earth you would be 15 pounds on the moon. This is because weight is the force of gravity acting on an object, and the force of gravity depends on the mass of the object. The force of gravity on the earth is six times greater than that of the moon, or, the force of gravity on the moon is 1/6 that of the earth. On earth, a person's weight would vary slightly between sea level and the top of a mountain. This is because the force of gravity is stronger the closer an object is to the center of the earth (or moon, or planet).
What is the force of gravity at the center of earth compared to its surface gravity would be equal to?
If the Earth would be a perfect sphere, you would experience no gravity in the center because all the mass around you would pull at you with the same strength in all directions, netting you a zero total force.
Describe gravity in terms of force?
gravity is the force by which the earth or any heavenly body attracts a mass towards its centre. the gravitational force depends on the mass of the heavenly body and the mass of the other body on which it acts. the gravitational force of the earth is 9.8 newtons. on a mass of 7 kgs on earth,the force would be 9.8 by 7 that is 68.6 newtons.
If earth stopped spinning would it loose atmosphere?
No, the atmosphere is held in place by gravity, not centripetal force. If the earth stopped spinning, there would be no coriolis force though. This would stop deflecting the moving air in the atmosphere.
Is Friction the most important force on Earth?
and because we would float off into space
What way does hurricane spin?
The hurricane spins counterclockwise due to the Coriolis force In the north if Canada was in the south it would spin clockwise. this happens because as the earth spins it veers the winds in the north west and in the south east
What would be the direction of the deflection knowing that the body can be affected by coriolis force?
Right in the northern hemisphere, left in the southern hemisphere.
What force stops the moon moving away from the Earth?
Gravity is the force holding the Moon to the Earth. Without gravity, the Moon would go flying off into space.Without gravity, the EARTH would go spinning off into space.Heck, without gravity, all of US would go spinning off into space.Gravity.
How does the coriolis effect affect astronauts in space?
Because astronauts orbiting the earth rotate around it much faster than the rest of us (once every 90 minutes or so rather than once a day) the effect of the Coriolis effect would be correspondingly stronger. Ordinarily, this force would still be too weak for astronauts to notice. However, because astronauts feel "zero gravity" (because they are falling towards the earth at the same rate as their ship) there are some situations in which the Coriolis effect might be more obvious to them; for example, objects floating in midair might slowly float back and forth* with a period equal to the ship's orbit time. *Technical discussion follows* Objects would actually follow elliptical or sinusoidal paths, and this floating effect would actually be a combination of three different effects: the Coriolis effect, along with the "centrifugal force", and the actual gravity of the earth. Whereas the Coriolis force depends on the velocity of a moving object, the last two effects vary slightly according to the radial distance from the center of the earth, and would therefore be most noticeable above or below the center of gravity of the spacecraft. For example, an astronaut resting above the spacecraft's center of mass would first begin falling (very slowly) towards the earth due to the decrease in centrifugal force with greater turning radius. Once moving, the astronaut would be affected by the Coriolis force, and pushed (very slowly) towards the front end of the spacecraft. Maximum drift speeds wouldn't exceed 1 cm/s for the even the largest rooms in the international space station. That said, I'm not an astronaut, and I don't know if astronauts have ever noticed this faint effect or not. I just did the math.
What is the what is the coriolis effect?
I believe the Coriolis Effect describes the direction that water swirls down the drain or in the toilet. North of the Equator, the water swirls counter-clockwise; south of the Equator, the water swirls clockwise. The Coriolis Force is not a real force but is a matter of positional realitivity on a spinning spherical surface (such as the surface of the earth) If you were to start at the north pole and walk directly south with no external forces acting on you - you would start to see (the farther south you went) that the earth would start moving faster and faster, west to east, beneath your feet. This is because the earth is spinning and you are stationary. This is not what happens in real life of course. If you started at the north pole and walked directly southward you would maintain your frame of reference with the earth, assuming the same west-east velocity as the earth to keep yourself stationary with the piece of earth surface you are currently on. In other words not only do you walk southwards but you also accelerate yourself to an west-east velocity to match the earth's velocity. Believe it or not but it is easier (less energy) to walk west-east or east-west than north-south or south-north because you don't have to change your velocity. Now when air blow from the north down to the south it doesn't want to accelerate west-east, so those of us who stand stationary on the earth seem to see some force pushing the moving air to the side. This apparent force has been called the Coriolis force - but really there is no such a thing.
What are the four factors that create wind?
The four factors are pressure gradiant force, coriolis force, friction force and gravity. Pressure gradient force move airs of higher pressure to lower pressure. Coriolis force prevents anything from moving in a straight line to earths oblate sphere. Friction rides the wind and without it air would travel parellel. Gravity because the power of gravity pulls air down.
What is the Coriolis effect?
Coriolis Effect:An apparent force, relative to the earth's surface, that causes deflection of moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the earth's rotation.In layman's terms, it is when a moving object appears to move or curve away from its intended destination due to the rotation or movement of its destination or its dispatcher.For example, two people are playing catch on a merry-go-round. Both of them are rotating with the merry-go-round as it spins. The thrower tosses the ball to the catcher. The ball follows a straight path, but because the catcher is moving the ball appears to curve away from him.History of the Coriolis effect is: an inertial force described by the 19th-century French engineer-mathematician Gustave-Gaspard Coriolis in 1835.Coriolis?You're best seeing something visual on this as it is easier to understand. There are plenty of good videos on YouTube.What you need to remember is that air at the equator is moving faster than air closer to the poles. Think about a bike wheel - the circumference of the outside of the wheel is much bigger than the circumference right next to the axis. So, for one full rotation of the wheel, the outside travels further in the same amount of time as the inside. In order to do this, it needs to move faster.The same goes for planet Earth. If air moving at the equator moves north, it is travelling faster than air in the area it is moving to. The air appears to be deflected to the right, you can think of it as overtaking the air in the new northern area it has moved to because it is moving faster.The Coriolis force accounts for global wind and ocean current patterns - a really important concept to get your head around. Coriolis effect is when a mass is moving in a rotating system. The movement is in a perpendicular direction.The curving of the path of a moving object from an otherwise straight pat due to Earth's rotation.
What is the force that deflects wind to the right in the northern hemisphere?
Basic wind circulation in both the Northern and Southern hemispheres is from west to east because that is the rotational direction of the Earth, which imparts energy to the air mass by friction. The circulation is complicated by convection and advection, but averages west to east (or left to right) at all latitudes over time.
What would happened to the magnitude of the gravitational force between the sun and Earth if earth were placed in Pluto's orbit?
The magnitude of the force would decrease greatly.
