In physics energy is the quantitative property that must be transferred to an object in order to perform work on or to heat the object. Dimensional formula is ml t 2.
Physics Equations Math Kinetic Energy Equations
When a force f moves an object through a distance s which is at an angle of θ then work w is done.
Physics formula energy. Power can be defined as the rate at which work is done i e. This article provides a comprehensive physics formulas list that will act as a ready reference when you are solving physics problems. The formula for potential energy of a system depends on the forces at work and the constituents of a system.
The law of conservation of energy states that energy can be converted in form but not created or destroyed. Physics formulas work power energy cheatsheet. The physics formulas for class 10 pdf is provided below.
Learning physics is all about applying concepts to solve problems. Potential energy of the spring. In physics practicals are as important as the theory.
It is the sum total of potential energy and kinetic energy which is the energy associated with the motion position of any object. Therefore the formula of mechanical energy will be. For the potential energy the formula is.
The si unit of energy is the joule which is the energy transferred to an object by the work of moving it a distance. You can even use this list for a quick revision before an exam. The formula for power is.
The law of conservation of energy is one of the basic laws of physics. Ep 1 2 k x k is the spring constant and x is the amount of compression or streching. The si unit of energy is joules j which is named in honour of james prescott joule.
The formula for the energy of motion is ke 5 m v2 where ke is kinetic energy in joules m is mass in kilograms and v is velocity in meters per second squared. Pe mg h m is the mass g is the gravitational acceleration and h is the distance. Potential energy is measured in si unit of joule.
Ek 1 2mv m is the mass v is the velocity. Students are suggested to revise the formulas regularly to prepare for the subject more efficiently. Click on class 10 science lab manual to get all the details on practicals.
In physics we can define energy as the capacity to do work. Check the list of class 10 physics formulas given below. The energy that an object has on account of its motion is called ke.
All macroscopic systems outside the atomic nucleus are either governed by the electromagnetic or gravitational forces. Energy is a conserved quantity. Mechanical energy kinetic energy potential energy.
Momentum p is the product of mass m and velocity v.
