How do you find tangential velocity?
Tangential velocity is equal to (mass x velocity^2)/radial distance
What is tangential velocity and tangential acceleration?
Vt=w*r where; * is multiply Vt is tangential velocity w is omega(angular mometum) r is radius
Is it possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration?
Yes. Imagine a ball on a rigid pole being swung around, and slowing down. It's tangential velocity is positive but it's tangential acceleration is negative
Why tangential acceleration is not produced in uniform circular motion?
Because there is no tangential force acting on the object in uniform circular motion. The proof that there is no tangential component of acceleration is the fact that the tangential component of velocity is constant.
How motion of satellite similar to the motion of an object in freefall?
A satellite is in free fall. When the only force acting upon it is gravity, it reacts freely to this gravity, accelerating towards Earth. That is to say, instead of going in a straight line, the velocity vector changes direction, towards Earth. If the satellite is fast enough to be in orbit, it will never actually fall on Earth; but the velocity vector changes all the time.
Is the velocity of any satellite 0 with reference to cos theta?
velocity of any satellite revolving around any planet is 0 with reference to cos theta. the velocity in circular motion is taken in tangential direction. when the velocity of any satellite is taken tangential , then it forms 90 degrees with the radius of the Earth. we know that cos90 = 0. therefore,velocity of satellites is 0 with reference to cos theta. but this contradicts the fact that " any body with 0 velocity would collide the Earth" stated by Issac Newton. scientists are still researching to get an appropriate answer to this question. - by d.s.rahul
A satellite in an elliptical orbit travels at constant what?
If the path is perfectly circular, yes, the speed is constant. This should not be confused with the velocity, because while speed is constant, its direction is not; therefore velocity is always changing.
How do you find tangential velocity?
Tangential velocity is equal to (mass x velocity^2)/radial distance
How is tangental velocity related to the moon falling around the earth?
The Moons tangential velocity is constantly changing in direction as it falls around the Earth.
What is the tangential velocity and centripetal acceleration of the earth moving around the sun?
Tangential velocity squared is GMs/r and velocity v =29814m/s and the centripetal acceleration is v2/r= 5.928 E-3 m/s2
Why dont satellites in orbit fall to the ground like a ball in orbit?
They're given enough tangential velocity ('sideways' speed, parallel to the earth's surface) so that the curve of the earth falls away just as fast as the satellite falls.
Draw a diagram showing the motion of a satellite around Earth is the satellite accelerating?
WikiAnswers cannot support diagrams - sorry. A satellite around the Earth will have an elliptical or (in some cases) a circular orbit. The satellite is constantly accelerating towards the Earth due to the gravity between the Earth and the satellite. However, because of the satellite's tangential velocity, it stays at a relatively constant distance from the Earth.
What is tangential velocity and tangential acceleration?
Vt=w*r where; * is multiply Vt is tangential velocity w is omega(angular mometum) r is radius
Is it possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration?
Yes. Imagine a ball on a rigid pole being swung around, and slowing down. It's tangential velocity is positive but it's tangential acceleration is negative
How do you convert radians per second to meters per second?
the tangential velocity is equal to the angular velocity multiplied by the radius the tangential velocity is equal to the angular velocity multiplied by the radius
Earth spins on an axis but which part of earth spins the slowest?
The Earth's rotation
Is the velocity of all the satellites zero since cos90 equals 0?
in my opinion, the velocity of any body moving in a circular path is directed in tangential direction. when the velocity is took tangential,its angle formed with reference to the earths radius is 90 degrees. we know that cos90 = 0. therefore,the velocity of the satellites revolving around the earth must be 0 with reference to cos theta. velocity of any satellite revolving around any planet is 0 with reference to cos theta. but this contradicts the fact that " any body with 0 velocity would collide the Earth" stated by Issac Newton. scientists are still researching to get an appropriate answer to this question. - by d.s.rahul
