Does the force of gravity do work on a satellite when it is in motion?
No, the force of gravity does not do work on a satellite when it is in motion because the direction of the force is perpendicular to the direction of motion.
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.
When did newton come up with gravity?
Sir Isaac Newton formulated his theory of gravity in 1687, with the publication of his groundbreaking work, "Principia Mathematica." This theory described the force of gravity as a universal force of attraction between all objects possessing mass.
Does gravity do work when objects fall?
Yes, gravity does work on objects as they fall. Work is done whenever a force causes displacement in the direction of the force, and in the case of falling objects, gravity is the force causing the displacement. This work is converted into the object's kinetic energy as it accelerates towards the ground.
The force that makes a boat float?
The force that is at work is gravity. If you are thinking of bouyancy, it is not a force.
The natural force at work on your vehicle on hills are?
gravity
What are adjectives for inclined planes?
slanted,easier work, simple machine,and force
Why does the force of gravity do no work on a bowling ball rolling down a bowling alley?
Work is definied in Physics as the Force acting on an object times the distance the object is moved by that Force, or W = fd Since Force is mass times acceleration (F=ma), and because the ball is on a surface that is perpendicular to the force exerted by gravity, there is no gravitational acceleration (a), hence no Force, so no Work is done by gravity.
How does a bungee jump work long answer?
Gravity and elastic force...
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.
Is work done if you lift a brick?
Yes, work is done when you lift a brick against gravity because you are exerting a force over a distance in the direction of the force of gravity. Work is defined as force multiplied by distance in the direction of the force, so lifting the brick requires work to be done.
Does a balance scale work by using force or gravity?
it works by reacting to the force created by the mass of your body being in a gravitational field. in short it works by using a force. but that force is because of gravity.
