Here are the statements that describe kinetic and potential energy, along with explanations for each:
-
Energy can be stored in the position of an object.
- True: This describes potential energy, which is energy stored due to an object's position or arrangement.
-
Energy is not present in a moving object.
- False: Moving objects possess kinetic energy, which is the energy of motion.
-
Energy can be stored in the position of the particles that make up a substance.
- True: This refers to potential energy at the microscopic level, such as in chemical bonds or the arrangement of particles in a system.
-
Energy exists as movement of the particles of a substance.
- True: This describes kinetic energy, which exists due to the movement of particles within a substance.
-
Energy is greater in faster-moving particles than in slower-moving particles.
- True: Kinetic energy increases with the speed of the particles (kinetic energy = 0.5 * mass * velocity^2).
-
Energy is lower in objects with greater mass than in objects with less mass.
- False: The amount of energy (kinetic or potential) is not solely determined by mass. For kinetic energy, a heavier object moving at a lower speed can have less energy than a lighter object moving faster.
In summary, the true statements are:
- Energy can be stored in the position of an object.
- Energy can be stored in the position of the particles that make up a substance.
- Energy exists as movement of the particles of a substance.
- Energy is greater in faster-moving particles than in slower-moving particles.
