How is work related to gravitational potential energy?
As we lift a body of mass m from ground level to a height h, then work performed will be mgh which is equal to the difference in gravitational potential energy at the ground level and at that height.
What is the potential energy of a 1.0kg mass 1.0 m above ground?
The potential energy of a body of 1.0 kg mass 1.0 m above ground is 9.8 joules.
Is it true that A body with zero acceleration cannot have any potential energy?
No, that is not true. Potential energy is measured relative to a given height. So if you have an object of mass m a height h above the ground (reference) in a gravity field g it has positive potential energy equal to mgh even though it is at rest and not accelerating
Why does an aircraft which has its engines above the fuselage produce less noise than one which has the engines below its body?
If the engine is placed above the body of the plane, the body acts as a shield that reflects or absorbs the noise going towards ground level, much the same way that a wall will muffle sound from an adjoining room
Why do you get an electric shock by touching a bare wire?
electric shock is a physiological symptom caused by an electric current flowing though the body. the current causes heating and, at higher levels, burns, and eventually death. The bare wire has an electric potential of some substantial voltage above ground. This potential causes a current to flow through your body to ground. if some other part of your body is not connected to ground, no current will flow. The current causes burning in your blood stream, your nervous system, and in you tissue. the current that flows through your body needs to be above about 10mA for you to perceive it as a shock. The voltage required to produce this current, by ohms law, depends upon the resistance between the point of contact and ground.

The fruiting body grows above ground.
A horses height is measured from ground to what body part like a shoulder blade?
from the ground to the wither.
A horses height is measured from the ground to what body part?
from the ground to the withers... i hand equals 4 inches
The mushroom that you see above the ground is actually?
fruiting body
Can abody have energy without having momentum?
yes. a body can have energy without momentum also. consider a body at a height 'h' m above the ground level , potential energy contained is = mgh but , as the velocity is 0 we can consider that the momentum of the body is 0
What is gravitational potential energy deduce an expression for it?
GPE is energy a body has by virtue of its position in a gravitational field. if the field is uniform (as near the surface of the Earth) then the work done to raise a body to a particular height above the earth is the same as the GPE gained by the body. Work done = force x distanced moved along the line of the force, W=Fd In this case, the force is the weight mg of the body and distance = height h above the Earth, so GPE = mgh
Which part of the mushroom can you see above the ground?

A mushroom that you see above ground is actually a?
Sex organ (or fruiting body) of a fungus.
