how are work and energy related explain the work-energy theorem
The work energy theorem relates the kinetic energy T and the potential energy V to the work of all external forces other than gravitational forces and spring forces U1-2 as O T1 V1- U1-2 T2V2. Work and energy are directly proportional to each other.

The measurement of work and energy with the same unit reinforces the idea that work and energy are related and can be converted into one another.
. Wnet ma xf - xo Given uniform acceleration vf2 - vI2 2axf - xo. O T1V1 T2V2 U1-2- O T1V1 T2V2 U1-2. Let us suppose that a body is initially at rest and a force vecF is applied on the body to displace it through dvecS along the direction of the force.
Potential energy also referred to as stored energy is the ability of a system to do work due to its position or internal structure. F is the final kinetic energy and K. To investigate the validity of the work-energy theorem.
The net work on a system equals the change in the quantity. The result based on Newtons laws that the net work done on an object is equal to its change in kinetic energy kinetic energy. Chance to take on the big one.
The work-energy theorem states that the net work done by the external forces on an object is equal to the change in kinetic energy of the object. The explosion of the burning mixture of fuel and air moves the piston. 10 N 10 kgms 2 so 10 J 10 kgm 2 s 2.
Substituting for axf - xo into our work equation we find that. The quantity 1 2mv2 in the work-energy theorem is defined to be the translational kinetic energy KE of a mass m moving at a speed v. W_textnetDelta E_kE_kf-E_ki The work-energy theorem is another example of the conservation of energy which you saw in Grade 10.
The work-energy theorem also known as the principle of work and kinetic energy states that the total work done by the sum of all the forces acting on a particle is equal to the change in the kinetic energy of that particle. The energy an object has by reason of its motion equal to latexfrac12textmv2latex for the translational ie non-rotational motion of an object of mass m moving at speed v. Work is said to be done when an acting force displaces a particle.
Work Energy transferred to or from an object by means of a force acting on the object. The work-energy theorem states that the change in the kinetic energy is equal to the amount of work done. 72 Kinetic Energy and the Work-Energy Theorem4.
2 is the kinetic energy of the particle it follows that dW dT. This is the Work-Energy theorem or the relation between Kinetic energy and Work done. 4 Equation 4 is the differential form of the work-energy theorem.
This equation is one form of the work-energy equation and gives us a direct relation between the net work done on a particle and that particles velocity. Examples are energy. The work-energy theorem states that the work done on an object by the net force is equal to the change in its kinetic energy.
Translational kinetic energy is distinct from rotational kinetic energy which is considered later. If an amount of work W is done on a system then the kinetic energy K of the system changes. You might get tired if you keep standing for a long time.
The principle of work and kinetic energy also known as the work-energy theorem states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. 10 J 10 Nm the units of force multiplied by distance. The joule J is the metric unit of measurement for both work and energy.
W Δ KE The engine of your motorcycle works under this principle. If there is no displacement there is no work done. F x ma x d v v v v axd ax 2 2 2 0 2 2 0 2 Work done by the force Energy.
To perform work energy has to be spent. Thus the work done can be related to the change in kinetic energy. The Work-Energy Theorem.
O is the original kinetic energy. This relationship is called the workenergy theorem. The change in the kinetic energy is equal to the amount of work done.
Thus work done Final kinetic energy - Initial kinetic energy change in kinetic energy. O T1 V1U1-2 T2 V2. W K mv 2 2 2 - mv 1 2 1 Equation 1 is a.
So work m 2 v22 - v12 12 mv22 - 12 mv12 final kinetic energy - initial kinetic energy. The quantity in the work-energy theorem is defined to be the translational kinetic energy KE of a mass moving at a speed. 2 The student is able to apply the concepts of conservation of energy and the work-energy theorem to determine qualitatively andor quantitatively that work done on a two-object system in linear motion will change the kinetic energy of the center of mass of the system the potential energy of the.
W net K. Energy is ability to do work. Translational kinetic energy is distinct from rotational kinetic energy which is considered later In equation form the.
To W From -W - Constant force. If K represents the change in kinetic energy of the body and W represents the work done on it. 71 2 K 1 mv2 Units.
Energy associated with the state of motion of an object. Then small amount of work done is given by. Work done by an object can be mathematically expressed as.
Work energy theorem states that the change in kinetic energy of an object is equal to the net work done on it by the net force. Work is said to be done whenever the force is applied to an object then the object is moved to a certain distance. In other words the work done on an object is the change in its kinetic energy.
W 1 2mv2 f 1 2mv2 i W 1 2 m v f 2 1 2 m v i 2. Musashixjubeio0 and 18 more users found this answer helpful. 1 Joule 1J 1 kgm2s2 N m II.
This explanation can be extended to rigid bodies by describing the work of rotational kinetic energy and torque. Wnet mvf2 - mvo2. It states that the differential work of the resultant of forces acting on a particle is equal at any time to the differential change in.
Where W is the work done by object measured using Joules. The Work-energy theorem explains the reasons behind this Physics of no work. When the displacement and the force applied are in an opposite direction.
