Work done against gravity work done against friction?
Umm I really don't know but let me think tho
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.
What is the work done against the gravity when a body is moved horizontally along a frictionless surface?
force?
What type of work is being done when pushing?
1) When you push an object on a flat surface work is being done against the force of friction (and air resistance). Work is calculated by the formula: Work = Force applied x distance moved in the direction of the force 2) When you push a spring to compress it, you are doing work against its stiffness In this case, Work = Force applied x 0.5 x decrease in length of spring 3) When you push something vertically upwards, you are working against gravity Here, Work = mass x earth's gravity x height raised
Is there any work done when a person takes a bucket to some distance?
The question is incomplete. If the bucket is taken in a horizontal plane then no work is done If the bucket is taken in an inclined plane then work has to be done against force of gravity

Does peristalsis work against gravity?
Yes, peristalsis will work against gravity.
What is the work done against the gravity when a body is moved horizontally along a frictionless surface?
force?
Can a coin have gravity power?
Any mass raised above the earth's surface has potential energy due to the work done in raising it against gravity

Why when you push an object across a desk the work done is not equal to the change in gravitational potential energy?
In this case, you are not doing work against the force of gravity, but against the force of friction.
Is walking is the work against gravity?
Walking across the room is not work against gravity.Walking up the stairs is work against gravity.Walking down the stairs is work with gravity.
Is there any work done when a person takes a bucket to some distance?
The question is incomplete. If the bucket is taken in a horizontal plane then no work is done If the bucket is taken in an inclined plane then work has to be done against force of gravity
What is work done by a coolie walking on a horizontal platform with a load on his head?
The displacement of the load is perpendicular to the direction of force therefore work done by the coolie against the force of gravity is zero.
What is gravitational energy definition?
Gravitational energy is a kind of potential energy - work done against a force.Gravitational energy is a kind of potential energy - work done against a force.Gravitational energy is a kind of potential energy - work done against a force.Gravitational energy is a kind of potential energy - work done against a force.
Why work is done on the pinwheel?
because of gravity
