Kinetic energy is the energy an object possesses due to its motion. It is a scalar quantity that depends on the mass and velocity of the object.
Kinetic energy is calculated using the formula KE = 1/2 * mv^2, where m is the mass of the object and v is its velocity.
No, kinetic energy cannot be negative. It is always a positive value since it is dependent on the square of the velocity.
Kinetic energy and potential energy are two forms of mechanical energy. Kinetic energy is the energy an object has due to its motion, while potential energy is the energy an object has due to its position or stored energy. They can be converted into one another, such as when an object falls and its potential energy is converted into kinetic energy.
Some examples of kinetic energy in everyday life include a moving car, a rolling ball, a swinging pendulum, and a person running. Essentially, any object that is in motion possesses kinetic energy.
