what is kinetic energy
Answers
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.
There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical.
Answer:
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
When you let go of that ball and let it fall, the potential energy converts into kinetic energy, or the energy associated with motion. There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical.
Chemists divide energy into two classes. Kinetic energy is energy possessed by an object in motion. The earth revolving around the sun, you walking down the street, and molecules moving in space all have kinetic energy. ... Calculate the kinetic energy in Joules possessed by each of the following objects.
An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity.
A baseball thrown by a pitcher, although having a small mass, can have a large amount of kinetic energy due to its fast velocity.
