"In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion."
Energy that an object possesses due to its motion.
"The kinetic energy of a non-rotating object of mass m traveling at a speed v is 1/2mv^2."
"It can be shown that the kinetic energy of an object is equal to the work needed to accelerate an object of mass m from rest to its stated velocity."
"The object maintains this kinetic energy unless its speed changes."
"The same amount of work is done by the object when decelerating from its current speed to a state of rest."
"The standard unit of kinetic energy is the joule."
"The English unit of kinetic energy is the foot-pound."
"In relativistic mechanics, 1/2mv^2 is a good approximation of kinetic energy only when v is much less than the speed of light."
"the mass and the velocity of an object contribute to its kinetic energy."
"An object's kinetic energy will increase if its mass increases."
"The kinetic energy of an object will become four times greater if its speed doubles."
"No, kinetic energy cannot be negative as it represents the energy possessed by a moving object."
"Kinetic energy can be converted to potential energy and vice versa in various systems according to the principles of conservation of energy."
"Kinetic energy is a scalar quantity as it only has magnitude."
"Examples of objects that possess kinetic energy include moving cars, flying airplanes, and rolling balls."
"The kinetic energy of an object will decrease by a factor of one-fourth if its velocity is halved."
"No, an object must be in motion to possess kinetic energy."
"The concept of kinetic energy demonstrates the conservation of energy, one of the fundamental laws of physics."
"Understanding kinetic energy is essential for calculating the amount of work done, analyzing collisions, and understanding the behavior of moving objects."
"No, according to the conventional definition and usage, kinetic energy cannot be negative."
