Ideal Power Force Equation

A horsepower is equal to 550 ft lbs and a kilowatt is 1000 watts.

Power force equation. For historical reasons the horsepower is occasionally used to describe the power delivered by a machine. It is a scalar quantity. Force is the product of time and power multiplied by distance.

The standard metric unit of power is the Watt. Power lb x fts Power ft lbshp The rate of doing workis equal to the rate of using energysince the a force transfers one unit of energy when it does one unit of work. So power applied force x velocity of the body If the displacement of the body instead of being along with the force is along a direction making an angle θ with the applied force then P Fv cos θ This equation represents a scalar product of two vector quantities.

Where s is the distance traveled. If you need additional help feel free to ask in the comments. This is easier to understand if you realize that Work Force x Distance.

Force and Power Using Newtons F ma we know that the force required to produce this acceleration again as a function of time is force t -45e6 acceleration t. In this case determine the values of both F and v and use this to calculate the power. Power is the rate of energy consumed in a unit of time Power Work time.

In British engineering system the unit of power is horse power hp. In physics work is a force applied over a distance and power is the rate at which work is done. Power Work done by the object or body Total time taken.

Distance can be calculated by dividing the products of time and power by the force. Power formula differs as per the required statements for example it can be different for force related objects and also can differ for electronic devices. Definition of horse power.
