Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Therefore, kinetic energy will be 12500 joules.In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Q.1: A car is traveling with a velocity of 10 m/s and it has a mass of 250 Kg. SI Derived Units List The SI unit of momentum (P) is kilogram meter per second (kg m/s) The SI unit of the magnetic field (B) is Tesla The SI unit of heat. Sometimes the power of motor vehicles and other machines is given in terms of Horsepower (hp), which is approximately equal to 745.7 watts. The SI unit of power is Watt (W) which is joules per second (J/s).

Table 1 Multiples and Submultiples of SI Units Table 2 Length Units Table 3 Area Units. What is Power We can define power as the rate of doing work, it is the work done in unit time. Dimensional formula SI& CGS unit of Physical Quantities. Ohms law says that the current running through some conductor material is directly proportional to the potential difference between two endpoints of the conductor.Įlectric current flowing through the conductor in amperes.įrequency is the revolutions completed per second or as the number of wave cycles. Physical Quantities: All quantities in terms of which laws of physics can be expressed and. The velocity with which the body is traveling Kinetic energy is the energy that is possessed by a body due to its state of motion. The pressure is defined as the amount of force applied per unit area of the object. PHYSICS FORMULA LIST 0. Formula: Work can be calculated by multiplying Force and Distance in the direction of force as follows. Weight is not anything but the force which an object experiences due to gravity. The Energy spent to do work in a unit amount of time is termed as Power. In physics, there are equations in every field to relate physical quantities to each other and perform calculations. The capacity to do some work is termed as Energy. The density of material shows the denseness of it in a specific given area.Īccording to Newton’s second law of motion, the force can be expressed by the product of mass and acceleration of the body. The average speed is the average of speed of a moving body for the overall distance that it has covered.Īcceleration is defined as the rate of change in velocity to the change in time. These links will take you to a page which you can print if you want to so that you can revise these equations. At the bottom of the page there are links to equations which the different examination boards have used in the past. If the force is being exerted at an angle to the displacement, the work done is W fd cos. Some basic but very important Physics formula is given below: 1) Average Speed Formula: This is a list of the equations which you might need to use for your GCSE Physics Exam. To express this concept mathematically, the work W is equal to the force f times the distance d, or W fd.
