What else can I help you with?
What is the work done against the gravity when a body is moved horizontally along a frictionless surface?
No work is done against gravity when a body is moved horizontally along a frictionless surface because the force of gravity acts perpendicular to the direction of motion. Work is only done when a force is exerted in the direction of motion.
Who did research on the motion of objects and the force of gravity?
Sir Isaac Newton is known for his work on the motion of objects and the force of gravity. He developed the laws of motion and the law of universal gravitation, which are fundamental principles in the field of physics.
When force is perpendicular to the direction of motion is work done?
No. At least not by the force that's perpendicular to the motion. When you push a baby stroller (or a car), you do work, but the force of gravity, downward and perpendicular to the motion, doesn't.
When is work said to be done against the force of gravity?
All bodies with mass are attracted to the Earth by gravity, so when a body is raised you must do work to raise it. This work is equal to force x height, if force is in Newtons and height in meters, the work is in units of Joules.
How much work is done on a satellite in a circular orbit about Earth?
The work done on a satellite in a circular orbit around Earth is zero because the gravitational force acting on the satellite is perpendicular to the direction of motion, so no work is done to maintain the orbit.
How much work is done on a satelite in circular orbit about earth?
In a circular orbit, a satellite is in free fall and moves with a constant speed, which means that the gravitational force acting on it provides the necessary centripetal force for its circular motion. Since the gravitational force is always perpendicular to the satellite's displacement, the work done on the satellite by gravity is zero. Therefore, no net work is done on a satellite in a stable circular orbit around the Earth.

The work done by gravity during the descent of a projectile motion is?
Zero, assuming there is no air resistance. Gravity does not do work in the horizontal direction during the descent phase of projectile motion because the force of gravity and the displacement are perpendicular to each other, resulting in no work being done by gravity.

Inward and outward forces when a satellite is orbiting Earth?
GRAVITY!!!!
How much work is done on a satellite in a circular orbit about Earth?
The work done on a satellite in a circular orbit around Earth is zero because the gravitational force acting on the satellite is perpendicular to the direction of motion, so no work is done to maintain the orbit.
What is the exertion of a force on an object called that produces motion in the direction of a force?
The exertion of a force on an object that produces motion in the direction of the force is called work. Work is calculated as the force applied multiplied by the distance moved in the direction of the force, and it is a measure of energy transfer.
What is amount of work done by a locomotive against gravity if it is travelling in a level of plane.?
If the locomotive is traveling on a level plane, the amount of work done against gravity is zero. This is because the force of gravity is acting perpendicular to the direction of motion. Work is only done when the force and displacement are in the same direction.
What forces do work on this system?
The forces that work on a system can include gravity, friction, tension, and normal force. These forces can affect the motion and equilibrium of the system.
How centripetal force and gravity keep a satellite orbiting?
Once an object is set into motion in a given direction it will continue in that direction unless a force prevents it from doing so. If you swing a ball around and around on the end of a string, it goes in a circle at the end of the string. The thing that keeps the ball from flying off is the string pulling on it. If you let go of the string the ball will sail off in a straight line in the direction it was moving at the moment you release the string.The ball wants to go in a straight line, the thing that prevents that is the string pulling on it. The string is exerting a centripetal force on the ball preventing it from flying away.Just like the ball, a satellite rotating around the Earth would fly off into space in a straight line if something weren't pulling it back toward the Earth. Earth's gravity is exerting a centripetal force, pulling on it, preventing the satellite from sailing away.
