force vs work vs power

You could run up a flight of stairs rapidly or you could climb the same stairs very slowly. It is generally represented as the product of displacement and force.

Work And Energy Ppt Download

An object can have a value for the power without doing any work.

. Power is work per time. A force of 50 N moves a 60 kg object along a rough floor at a constant speed of 25 ms. 1 kilocalorie 1 Calorie food Power.

Shows you how to determine the work done by a force from the force vs. Now we can find Power. Definition and Mathematics of Work.

You can walk up a flight of stairs or you can run up a flight of stairs. Power is the amount of energy that is transferred in a unit of time. Angle 180 degree is force and work are opposite direction.

Angle 90 degrees if force is perpendicular to work. Ad Browse discover thousands of brands. Shows you how to determine the amount of work done on a object from the force vs.

The formula for calculating the force is Work Force Displacement. Work is measured in joules whereas power is measured in watts. The SI unit of power is Watt W.

However in the running case you develop more power. This system contains most of the metric units you are used to like meters and kilograms but also includes units for many other physical and. Angle 0 degrees if force and work are in same direction.

The work done is equal to the area under the force vs distance gra. Main Differences Between Work and Power. Either way you do the same amount of work because you apply the same force equal to your weight through the same distance the height of the stairs Power is work per time.

Lesson 1 - Basic Terminology and Concepts. The SI unit of work is Joules but the SI unit of power is Watt and Horsepower in case of motor. One joule of work is done when a force of one newton is applied through a distance of one meter.

In order to determine power we need to determine the value of Work. C What power is being used by this pushing force. Either way you apply the same force through the same distance so you do the same amount of work.

The girl had more power than the boy. The SI unit of work is Joule J. A child pulls a toy car along a smooth frictionless floor.

Lesson 2 - The Work-Energy Relationship. The forces in newtons N and distances in meters m are shown in the graph below. The work done is equal to the area under the force vs.

A horsepower is equal to 550 ft lbs and a kilowatt is 1000 watts. The rate of doing work is equal to the rate of using energy since the force transfers one unit of energy when it does one unit of work. B How much work is done by the weight force in 25 s.

Find deals on power vs force on Amazon. Based on the information in the graph. The formula of calculating power WorkTime.

The girl did more work and had more power than the boy. That is if you do the same amount of work in a shorter time it takes more power. The girl had less power than the boy.

If the object does any work the value of the power cannot be zero. In most of the world the International System of Units SI - from the French Le Système International dUnités also referred to as the metric system is accepted as the standard set of units. Work is determined by factors like force and displacement on contrary power is determined by work done and time.

The force forms a 30 angle with the horizontal direction a How much work is done by this pushing force in 25 s. Work is the energy required to move an object whereas power is meant as the energy spent to move the object. Read customer reviews find best sellers.

Calculating the Amount of Work Done by Forces.
