What is the work done by a satellite revolving around the earth?
zero When a satellite moves around the Earth, then the force of gravity on the satellite is perpendicular to its displacement. Hence, the work done on the satellite by the Earth is zero.
How much work is done on the satellite during one complete orbit of the earth?
The total amount of (net) work done by gravity as a satellite makes a complete orbit is zero. The gravitational force has a component in the direction of the satellite's motion as the satellite moves toward the Sun (or Earth, or whatever).
Does Earth do work on a satellite?
Because the speed of the satellite doesn't change, its kinetic energy doesn't change (E=12mv2); so no work has been done on it. If work had been done on it, its kinetic energy would have increased. What do you mean?
Does gravity do work on a satellite orbiting the earth?
So it is not you who does any work. A satellite in a perfectly circular orbit is moving tangentially to the earth's surface – parallel to the ground. Gravity is pulling straight downwards, perpendicular to that orbital path. So gravity does no work.
Why does satellite revolves around earth in a circular orbit?
But the gravitational force always try to pull the satellite towards itself, so the satellite continuously changes its direction without changing its speed so as to revolve in a circular orbit and centripetal force can balance the gravitational force.
What is the work done by the force of gravity on a satellite moving round the earth justify Youranswer?
Justify your answer. The work done by the gravitational force is zero. This is because the satellite is moving in a circular orbit. Thus the direction of displacement of the satellite is perpendicular to the force of gravity.
What is the work of a satellite in orbit?
A satellite orbits Earth when its speed is balanced by the pull of Earth's gravity. Without this balance, the satellite would fly in a straight line off into space or fall back to Earth. Satellites orbit Earth at different heights, different speeds and along different paths.
What is the work done by the force of gravity on a satellite moving around the sun?
The work done by the gravitational force is zero. This is because the satellite is moving in a circular orbit. Thus the direction of displacement of the satellite is perpendicular to the force of gravity. Hence work done is zero.
What is the work done on a satellite by the Earth’s gravitational force Why?
The work done by the force of gravity on a satellite moving around the earth is zero.
What is the work done on a satellite by the earth’s gravitational force Why?
The work done by the force of gravity on a satellite moving around the earth is zero.
What will be the work done a by the force of gravitation acting on a satellite revolving around a planet?
The work done by the force of gravity on a satellite moving around the earth is zero.
What is the work done by the force of gravity in the following cases a satellite moving around the earth in a circular orbit of radius 35000 km?
zero Therefore, the work done is zero. So the satellite moving around the earth in a circular orbit, the work done is zero.
What is the work done when satellite moving around the earth in a circular Orbitof radius of 35000km?
zero Therefore, the work done is zero. So the satellite moving around the earth in a circular orbit, the work done is zero.
How do you calculate total work done by gravity?
The work done by gravity is W=mgh.

Why does a satellite revolve around the Earth in a circular path?
But the gravitational force always try to pull the satellite towards itself, so the satellite continuously changes its direction without changing its speed so as to revolve in a circular orbit and centripetal force can balance the gravitational force.
What is the work done when satellite moving around the Earth in a circular Orbitof radius of 35000km?
zero Therefore, the work done is zero. So the satellite moving around the earth in a circular orbit, the work done is zero.
How much work is done by gravitational force of Earth acting on a satellite around it in a circular path give reason for your answer?
No work No work is done by the gravitational force of earth acting on a satellite moving around it in a circular path because the gravity is always pointing towards the center of the earth which provides the centripetal force required for circular motion and the satellite is going tangentially, the angle between is 90 degrees.
What is the work done by the gravity on a satellite moving round the earth justify your answer?
zero The work done by the force of gravity on a satellite moving around the earth is zero.
What is the work done by gravity on a satellite?
zero The work done by the force of gravity on a satellite moving around the earth is zero.
Is work done by gravity zero?
So gravity's not causing this displacement at all, and therefore we can say the work done by gravity is zero, because gravity's not the one that displaced this body.
What is work done formula?
To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
What force keeps satellites in circular orbit?
gravity That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity. Newton was the first to theorize that a projectile launched with sufficient speed would actually orbit the earth.
What force keeps a satellite in orbit?
the gravitational pull A satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it.
How much work is done by the gravitational force of Earth?
zero Work done is zero since force and displacement are in perpendicular direction, i.e. w=0w=0. Was this answer helpful?
What is the work done by the gravitational force of the earth?
W=mgh The work done by gravity is W=mgh.
What is the work done by the force of gravity on a man walking on the horizontal road?
Work done against gravity is zero as there is no displacement along or opposite to the direction of force of gravity.
Is work done by gravity negative?
Gravity does negative work here because gravity goes in the opposite direction as the displacement.
Can work done be negative?
When the direction of motion of the body and the force acting on the body is opposite, work done is negative.
How do you find the rate of work done?
Because power is a measurement of how much work is done in a given time, power can be calculated based on work and time. To find power, divide the amount of work by the time it takes to do the work. Remember that work is measured in joules. Power is often measured in joules of work per second.
