what is kinetic energy in ph
Answers
Answer:
Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. ... Note that energy is a scalar quantity, i.e., it does not depend on direction, and it is always positive
Answer:
What is Kinetic Energy?
The kinetic energy of an object is the energy that it possesses due to its motion. Kinetic energy definition is given as:
The energy of an object because of its motion or the energy gained by an object from its state of rest to motion.
How is kinetic energy different from potential energy?
Kinetic energy is due to an object’s motion whereas potential energy is due to an object’s position or state. Velocity is an important factor while calculating an object’s kinetic energy. However, velocity has nothing to do with an object’s potential energy.
Formula of Kinetic Energy
Following is the formula of kinetic energy:
KE=12mv2
Where,
KE is the kinetic energy of the object
m is the mass of an object
v is the velocity of an object
Kinetic energy is an example of scalar quantity which means that the quantity has only magnitude and no direction.
Unit of Kinetic Energy
The SI unit of kinetic energy is Joule which is equal to 1 kg.m2.s-2.
The CGS unit of kinetic energy is erg.
