Define kinetic energy
Answers
Answer:
Kinetic energy is the energy an object has because of its motion.
Explanation:
What is kinetic energy?
Kinetic energy is the energy an object has because of its motion.
If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
Kinetic energy can be transferred between objects and transformed into other kinds of energy. For example, a flying squirrel might collide with a stationary chipmunk. Following the collision, some of the initial kinetic energy of the squirrel might have been transferred into the chipmunk or transformed to some other form of energy.
How can we calculate kinetic energy?
To calculate kinetic energy, we follow the reasoning outlined above and begin by finding the work done, W, by a force, F, in a simple example. Consider a box of mass m being pushed through a distance d along a surface by a force parallel to that surface.
