True
False. All objects do not have kinetic energy. Kinetic energy is the energy an object possesses due to its motion. Objects at rest do not have kinetic energy.
False. Kinetic energy is related to an object's motion or speed, not its height. Potential energy is related to an object's height, while kinetic energy is related to its motion.
False. Electrical energy is the energy associated with electric charge and the flow of electric current. It is not the total kinetic and potential energy of the particles in an object.
True. In a substance, all molecules possess the average kinetic energy value because temperature is a measure of the average kinetic energy of the particles in a substance.
False. When temperature increases, the average kinetic energy of the particles also increases. This is because higher temperature means that the particles are moving faster and with more energy.
False. All objects do not have kinetic energy. Kinetic energy is the energy an object possesses due to its motion. Objects at rest do not have kinetic energy.
No. In gases, 'Absolute temperature' is proportionally related to the kinetic energy of the particles. Therefore, increase in temperature results in increase in the kinetic energy of the particles.
False. A stick of unlit dynamite contains potential energy, not kinetic energy. Kinetic energy is the energy of motion, while potential energy is the stored energy an object possesses due to its position or state.
False. Kinetic energy is related to an object's motion or speed, not its height. Potential energy is related to an object's height, while kinetic energy is related to its motion.
False. Electrical energy is the energy associated with electric charge and the flow of electric current. It is not the total kinetic and potential energy of the particles in an object.

False. Kinetic energy is indeed the energy possessed by a body in motion, not by a stationary object. The energy exhibited by a stationary train would typically be in the form of potential energy, such as gravitational potential energy due to its position on the tracks.
False. Reflecting panels do not use the kinetic energy of movement. Instead, they reflect light to redirect its path or concentrate it onto a specific area for various purposes like energy generation in solar panels or lighting in photography.
