what is 1 2mv 2 KE kinetic energy m mass of a body v velocity of a body The Kinetic Energy Calculator uses the formula KE 1 2 mv 2 or kinetic energy KE equals one half of the mass m times velocity squared v 2
Since this is the work done on the object by the force it is equal to the energy transferred to the kinetic energy store of the object In other words it is the energy the object has gained because it is moving its kinetic energy no less Ek mv2 Less abstract and only using basic arithmetics the story goes like this When accelerating a body by applying a constant force F along a distance s the body gains energy according to E F s which is just the definition of mechanical work According to Newton s second law F ma

The equation for kinetic energy 1 2mv 2 comes from the work energy theorem which states that the work done on an object is equal to the change in its kinetic energy In other words the kinetic energy of an object is equal to the work required to accelerate it from rest to its current velocity Doubling the mass of a moving object doubles the energy it has in its kinetic store Doubling the speed of an object increases the energy it has in its kinetic store by four times The energy an object has in its kinetic store of energy is found using the equation Ek mv
The equation for kinetic energy is 1 2 M V squared So as mass increases kinetic energy increases like the more massive cheddar versus the Swiss and as velocity increases kinetic energy increases even more like the speedy Swiss versus the slower cheddar K 1 2mv 2 You can take any equation of motion solve for v and then substitute in the equation above I could provide more help if you gave the specific equation

I don t like this answer since it uses the Work Energy Theorem when saying that kinetic energy is the work done to accelerate a particle from rest to a final speed and the WET is deduced by knowing the kinetic energy is 1 2mv2 1 2 m v 2 So the argument is circular In short the half in kinetic energy comes from a Taylor expansion of the relativistic energy formula since the formula 1 2mv2 is only an approximation of special relativity The half in kinetic energy can also be explained as an integration factor from the work energy theorem
1 What is the equation for kinetic energy The equation for kinetic energy is KE 1 2mv 2 where m is the mass of the object and v is the velocity or speed of the object 2 How does kinetic energy relate to an object s motion Kinetic energy is the energy an object possesses due to its motion The equation Mgh 1 2mv 2 is known as the Law of Conservation of Energy It states that the total mechanical energy of a system consisting of potential energy Mgh and kinetic energy 1 2mv 2 remains constant as long as
