work vs power example

Work is for example the force required to move a 5 pound rock a distance of 20 feet - it does not matter how quickly the rock moves 20 feet the Work is the same. The energy that the object consumes on average working per unit time is average power.

Conservation Of Energy Conversion Of Potential Energy To Kinetic Energy Potential Energy Physics Topics Energy Work

Power Work time or P W t.

. It is generally represented as the product of displacement and force. There is no point in expressing the. Power and work are two very important concepts discussed in mechanics.

That is expressed as Power. The following diagram gives the formula for power and work done. The SI unit of work is Joule J.

Work Force Displacement. Work and power are similar to each other as both use energy. Refers to an activity involving a force and movement in the directon of the force.

Difference between work and power is based on the amount and rate of energy consumed. Difference between Work and Power. Work and power might seem similar to each other as both involves energy.

Here in the context of work and energy power is simply the rate of doing work. The SI unit of power is Watt W. A force of 20 newtons pushing an object 5 meters in the direction of the force does 100 joules of work.

Work describes the amount of energy. Work is a scalar quantity. Work is the amount of energy necessary to move an object from one point to.

The power rating relates to how rapidly the car can accelerate the car. Power is the rate of energy consumed in a unit of time Power Work time. If the angle between the force and displacement is 30o find the work done by the force.

If a carton of books is. Work is energy or. A box is pulled with a force of 25 N to produce a displacement of 15 m.

Power is a scalar quantity. In exercise its the rate of performing muscular work with potential energy. Force F 25 N.

Power vs Work. The point is that for the same amount of work power and time are inversely proportional. The main difference between work and power is the amount and rate of energy used.

Power Electric potential x Current or P E x I. Work is referred to as the process of energy that is transferred to an objects motion by applying force. Work vs Power.

Example 25 N force is applied to a box and box moves 10m. Work is the total amount of energy that is used to shift an object from one place to another by applying an outside force for example. A car engine is an example of a machine that is given a power rating.

Power describes the rate of energy transfer. This formula makes the point that the power depends on both the amount of electricity being.
