What is the difference between work done by and work done on?

Work done on the system means something outside the system did something (other than heat flow into the system) to increase the internal energy of the system. Work done by the system means the system’s internal energy decreased as it did work on something outside the system.

What is the difference between power and average power what is the unit of power?

The rate of doing work is called power. The basic difference between average and instantaneous power is that average power is the ratio of total work and total time. While instantaneous power is the limiting value of average power. The rate at which work done is often interest in practical applications.

What is difference between work and energy?

Work is the ability to supply force and a change in distance to an object. Energy is the ability to supply or create work.

What is the difference between work and work net?

Net Work and the Work-Energy Theorem. Net work is defined to be the sum of work done by all external forces—that is, net work is the work done by the net external force Fnet. In equation form, this is Wnet = Fnetd cos θ where θ is the angle between the force vector and the displacement vector.

What are examples of work being done?

Work is done whenever a force moves something. Everyday examples of work include walking up stairs, lifting heavy objects, pulling a sledge and pushing a shopping trolley. Whenever work is done, energy is transferred from one place to another.

What is the difference between average power and instantaneous power become equal if work is done at?

The average power and Instaneous power become equal if work is done at uniform rate.

What is the difference between power and average power Class 9?

Important Points About Power (c) It could change so there are two ways to measure power. Instantaneous: The power at any given moment of time. Average: The total energy used divided by total time is the average of all the instantaneous powers.

What is the difference between work and energy explain the different types of work with examples?

It is also referred to as the force which works at a certain distance. Energy deals with the capacity of an object to do the work. The SI unit of physics is joules….Difference Between Work and Energy.
