Q:
# How do you calculate percent efficiency?

A:
### Quick Answer

**Percent efficiency is calculated by determining the actual output and then dividing by the maximum possible output.** The result is multiplied by 100 in order to move the decimal two places to the right.

The formula for calculating percent efficiency works in much the same manner as the formula for calculating the percentage of anything in the sense that it is nothing more than the division of the actual by the total. Because of this, it is, by definition, impossible to have a percent efficiency that is greater than 100. In physics, the efficiency of most things is necessarily lower due to friction and the laws of thermodynamics.

Q:
## How is efficiency defined in physics?

A:

Full Answer >**One of the most common definitions for efficiency in physics is a measurement of how much of the desired work or product is obtained from each unit of energy invested into that task or product.**An additional definition of efficiency is based on the total amount of energy required to produce a specific amount of a product. Both definitions fall under the category of first law efficiency because they are derived from the first law of thermodynamics.Filed Under: -
Q:
## How do you find a resultant vector?

A:The resultant vector is calculated as the sum between two or more vectors. When adding vectors together, their direction and magnitude must be taken into account while calculating the resultant vector.

## How do you calculate buoyancy?

A:

Full Answer >**Buoyancy is an objects ability float in a liquid and it is measured in terms of buoyant force, which is calculated with the following formula: buoyant force = pressure times area.**Archimedes' principle is used to explain this phenomenon.Filed Under: -
Q:
## How do you calculate normal force?

A:To calculate the normal force on an object, draw a free body diagram, determine the surface's angle, factor in the other present forces, and solve for the normal force. Note that the normal force is perpendicular to the surface the object sits on.
