WHAT CAN 1000 joules do?
A unit with up to 1000 joules of surge protection is adequate for these small electronics. A surge protector with 1000 to 2000 joules will provide sufficient protection for power tools and office equipment such as printers, copiers and routers.
What is 1 joule of work in KG?
Then, in terms of SI base units a joule is equal to a kilogram times meter squared divided by a second squared (kg×m2s2) ( kg × m 2 s 2 ) . Another common unit of energy that is often used is the calorie (cal), which is equivalent to 4.184 J.
Does a joule measure work?
Scientists use the joule to measure work. One joule is equal to the work done by a force of one newton to move an object one meter in the direction of the force. To raise an apple one meter in the air, you must use one joule of kinetic energy.
What can I do with 1 joule of energy?
In physical terms, lifting an apple one meter takes 1 joule of energy. This should not be confused with a watt which is a unit of power and a rate of how fast energy is used.
Which is the correct definition of 1 joule?
Answer Wiki. The joule is a derived unit of energy in the International System of Units. 1 Joule definition:- 1 joule of work done is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre.
Is the SI unit of work the same as the Joule?
This definition causes the SI unit for energy is the same as the unit of work – the joule (J). Joule is a derived unit of energy and it is named in honor of James Prescott Joule and his experiments on the mechanical equivalent of heat. In more fundamental terms, 1 joule is equal to:
How is joule related to thermal engineering energy?
Joule is a derived unit of energy. It is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre. Thermal Engineering Energy is generally defined as the potential to do work or produce heat.
Which is more one joule or one watt?
One joule is equal to the energy used to accelerate a body with a mass of one kilogram using one newton of force over a distance of one meter. One joule is also equivalent to one watt-second. Joule, James Prescott 1818-1889.
