What is 1j of work class 9?

1 J is the amount of work done by a force of 1 N on an object that displaces it through a distance of 1 m in the direction of the applied force.

What is the energy of 1 joule?

One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m).

What is one joule work class 8?

1 joule work is defined as the amount of work done to cover a distance of 1m in the direction of force when the force of 1N is applied on the body.

What is the formula for 1 joule?

Joule is the SI unit of work done. Therefore, the dimensional formula of Joule is the same as that of the work done. On substituting equation (2) and (3) in equation (1) we get, Work (Joule)= F × D = [M1 L1 T-2] × [L1] = [M1 L2 T-2].

What do you mean by 1 joule?

joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.

What is work done?

The work done by a force is defined to be the product of component of the force in the direction of the displacement and the magnitude of this displacement. Formula. Work can be calculated by multiplying Force and Distance in the direction of force as follows. W = F × d. Unit.

Is joule a unit of work?

The SI unit for work and energy commonly used in drawing is the joule (J), which is equivalent to a force of one newton exerted through a distance of one meter (m).

How do you calculate Joules at work?

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton. meter (N. m).

What is the unit of 1 joule?

What is work class 9?

Work (W) Work is defined as a force acting upon an object to cause a displacement. It is expressed as the product of force and displacement in the direction of force. W=F x s.

What is SI and CGS unit of work?

S.I. unit of work is Joule and C.G.S. unit of work is erg. Relation between joule and erg : 1 joule = 107 erg. We know that, 1 Joule = 1 N × 1 m. ⇒ 1 J = 105 dyne X 102 cm =107 dyne cm. Hence, 1 joule = 107 erg.
