Why don't you feel the motion of the earth around the sun?
We do not feel the sun's gravity because Earth orbits the sun and so is essentially in freefall. Objects in freefall seem weightless from a viewpoint that is freefalling with them. We, of course, do not feel weightless because of Earth's gravity, which is independent of the sun's gravity.
Is a satellite circling the Earth above the atmosphere in free fall?
Yes it is in free fall because gravity is the only force acting on it. (no air resistance)
What are the two forces acting when a space shuttles take off?
The two forces acting on a space shuttle during take off and throughout its ascent through the atmosphere are Thrust and Weight. Moreover, there is also a drag force in the direction of the weight, i.e., opposite to the motion of the space shuttle. Hope that's what you were looking for. :)
Why do we experience weightlessness in space?
Because there are no contact forces acting on us. Gravity is the only acting on us. A body experiences weightlessness when gravity is the only force acting on it.
What keeps the earth from crashing into the sun?
In short, gravity. Outward pressure from the core is equal to inward pressure of gravity, which is also known as hydrostatic equilibrium.
How do you calculate the pressure acting on an organism below the ocean's surface?
add 1 atm (atmosphere) for every 10 meters below the surface
What will happen to you at 5000 feet below sea level?
"Most likely you will be crushed by the force of water, you see the more you go down in the ocean the more pressure there is. That's why many animals that live in the ocean are not discovered yet because they live so deep down that we cannot go down or else we will be crushed and most likely die."Edit: There is not a question of probability here. No "most likely" is needed. You will most certainly die due to pressure far before you come close to 5000ft unless in some kind of underwater vessel.5000ft / 33 ft per ATM * 14.7psi per ATM =2 227.27psi!!!- now multiply the Pounds per Square Inch by the Surface Area of your body... and that will give you a rough number for the amount of pressure acting on your body.(33 ft = depth at which the pressure of the atmosphere doubles. Every additional 33ft is another atmosphere of pressure. 1 atmosphere is what you are feeling now, sitting at your computer... hopefully... :) )(14.7psi = 1 ATM, standard conversion factor)
What is the meaning of pressure in drama?
acting
How can the pressure acting on the surface be increased by the force acting on the surface?
Simply pressure is the force per unit area. So Pressure is directly proportional to the force applied. Hence by increasing the force we can increase the pressure.
What are the forces acting on a chair when you get off a chair?
Assuming the chair (and you) are standing on a planet, in an atmosphere (so you don't suffocate/explosively decompress), the chair will continue to be acted upon by gravity. In addition, air pressure will press upon it. In an open planetary setting, air pressure is often explained as gravity pulling the weight of the atmosphere upon the objects it envelopes.
What are some examples of the atmosphere acting as a system?
global wind pattern
How would you demonstrate the presence of atmospheric pressure?
Suck the air out of a container and watch it being crushed. Look at a balloon. Its round shape tells you that the pressure (atmospheric) from outside acts equally from all directions. Now take that balloon up a mountain and watch the balloon get bigger. There is less atmospheric pressure acting on the outside of the balloon the higher you go so the pressure inside the balloon makes the balloon bigger.
How is pressure realted to force and area?
Pressure is the force acting per unit area.
On pneumatic thermostat what is the difference between direct acting and reverse acting?
A Direct Acting (DA) pneumatic thermostat increases branch line pressure as temperature increases. A Reverse Acting (RA) pneumatic thermostat decreases branch line pressure as temperature increases.
