How do you define power in physics?

power, in science and engineering, time rate of doing work or delivering energy, expressible as the amount of work done W, or energy transferred, divided by the time interval t—or W/t. A given amount of work can be done by a low-powered motor in a long time or by a high-powered motor in a short time.

What is the difference between power and work physics?

Work is defined as the process of energy transfer to the motion of an object through the application of force. The SI unit of work is Joule. Power is defined as the amount of energy transferred in unit time.

What is the difference between force and work describe with example?

Force is defined as the rate of change of momentum (momentum is mass multiplied by velocity) with respect to time. Work is the product of displacement and the component of force in the direction of displacement. If work is done, then the kinetic energy of an object changes.

What is the difference between force and work?

What is force vs power?

Force vs. Power. The concepts of force and power seem to convey similar meanings and are often confused for each other. But in physics, they are not interchangeable. Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element.

What is force and power?

Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element. Force and power can both be described and measured, but a force is an actual physical phenomenon, and power in itself is not.

What is force and work?

The term “work force” is used in several different ways. In the first sense, it is the entire pool of people who are available and willing to work, including both unemployed job seekers and people who have jobs. In the second sense, it refers specifically to a pool of people within a specific industry or company.

How does force work?

Forces work in pairs. They push or pull in opposite directions. When pairs of forces are equal they are said to be balanced. Tug-of-war teams remain still when each pulls with the same strength. A team falls when one side is stronger and the forces are unbalanced.
