What is the best definition of power in science?

Scientific definitions for power The source of energy used to operate a machine or other system. The rate at which work is done, or energy expended, per unit time. Compare energy work.

What is a power easy definition?

Power is defined as the ability to act or have influence over others. An example of power is the strength needed to run five miles. Power means to supply with energy or force.

What is power in science Short answer?

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.

What’s the meaning of power in physics?

Power is the amount of energy that is transferred per second.

How do you calculate power in science?

The equation for power is P = W/t. P stands for power (in watts) W stands for the amount of work done (in Joules) or energy expended (in Joules) t stands for the amount of time (in seconds)

What does power mean in science?

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 definition of power according to physics?

In physics, power is the amount of energy transferred or converted per unit time . In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity.

What does power depend on physics?

Power is a scalar quantity. It does not depend only on total amount of work done, but on how long it takes to do that work. If time takes to do a particular work is less, then its power is more. Power is the rate at which work is done or energy is transferred in a unit of time.
