What else can I help you with?
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.
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.
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.
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.
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.
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.
What is work done by a coolie walking on a horizontal platform with a load on his head?
The work done by the coolie is zero because the force he exerts is in the vertical direction (lifting the load against gravity) while the displacement is in the horizontal direction. Work is only done when the force and displacement are in the same direction.
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 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 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.
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.
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.
What is the direction of the force of gravity?
The force of gravity acts towards the center of mass of the object in question.
How much work is done by gravity on the two-block system?
The work done by gravity on the two-block system is equal to the force of gravity multiplied by the distance the blocks move in the direction of gravity.
What direction does the force of gravity apply to the rollercoaster car?
From what I know, Force of Gravity always acts in the vertically downward direction.
