What is P MV law?
Newton's third law states that for every action there is an equal and opposite reaction. Momentum and force are defined mathematically as follows: p = mv (momentum = mass * velocity) F = ma (force = mass * acceleration) So, to summarize: Newton's First Law describes the Conservation of Momentum.
Why gravitational potential energy is MGH?
Work done against gravity in lifting an object becomes potential energy of the object-Earth system. The change in gravitational potential energy, ΔPEg, is ΔPEg = mgh, with h being the increase in height and g the acceleration due to gravity.
What is potential energy?
Potential energy of a body is due to its higher position above the earth and it is equal to work done on the body against gravity in moving the body to that position . A body of mass 'm' is raised to a height 'h' above the ground . The force acting on body is gravitational pull of earth that is m×g.

The gravitational potential is the potential energy per unit of mass, so the difference in potential energy a
What is friction force?
Friction is just a force which comes into action to provide resistive force against relative motion.
What would happen if friction was really a force providing negative accleration?
If friction was really a force providing negative accleration, it would do so even if two bodies in contact are not in relative motion, hence intitiating a motion of its own, which is not possible.

How to find the work done to raise an object of mass m through a height?
Thus , the work done to raise an object of mass m through a height h = Force × distance ( which is height in this case) = mg×h=mgh.
What is PE energy?
The PE ie potential energy is the work done in raising the object to a height h.
What is the difference between gravitational potential and electric potential?
Here the gravitational potential energy is defined as the energy possessed by an object by virtue of its position relative to others. Elastic potential energy is defined as the energy possessed by virtue of stresses within its body and an electric potential is defined as the energy possessed by an object by virtue of the total charge stored within.
Why are dams built on rivers?
But do you know the reason behind this? Here, the potential energy possessed by water is used to harness electrical energy. Water raised to a certain height gains potential energy with respect to the ground due to the gravitational force acting on it. This energy is used to turn the blades of turbines positioned in the dams that eventually helps in the generation of electricity.
Why does water raise to a certain height gain potential energy with respect to the ground?
Water raised to a certain height gains potential energy with respect to the ground due to the gravitational force acting on it. This energy is used to turn the blades of turbines positioned in the dams that eventually helps in the generation of electricity.
What is potential energy?
Potential energy is defined as the energy stored in an object. Potential energy can be divided into many types; Gravitational potential energy, Elastic Potential energy, Electric Potential Energy etc. Here the gravitational potential energy is defined as the energy possessed by an object by virtue of its position relative to others.
What is the mass of an object m?
It is given that mass of the object m = 0.8 kg.#N #Since the potential energy of the object is only dependent on its height from the reference position, we can say that,
What is the unit of energy?
The SI unit of energy is Joules and the dimensional formula is given as:
What does "empty" mean in Arabic?
From there, the concept kept passing on. The Arabic translation of empty/nothing was safara which meant 'to be empty'. Hence, the Arabs began using the word sifr which eventually made its way to Europe and eventually the word cipher started to be used. But the word cipher underwent changes in meaning to 'any numeral' and finally to 'a coded message'. The existing word in English for nothing was naught. H
What is GPE reference point?
In a similar way, GPE is going to need a reference point, a point that we are going to call zero. You can choose any point you like. If you lift something up and the object gains GPE, you can measure from the table top, from the floor, from the ground outside, from sea level etc.

What happens when force and displacement are in opposition to each other?
If force and displacement are in opposition to each other, the work done is negative.
What happens when the applied force is in the opposite direction as the displacement of the moving object?
If the applied force is in the opposite direction as the displacement of the moving object, work can be negative.
Why is kinetic energy always positive?
Because an object’s mass can never be zero and the square of velocity is positive, therefore kinetic energy is always positive.

On the graph, the green shaded area in the figure is OPQR which is also Fd. Hence area under the force-displacement curve measures the work done.
