Question

energy of an object in motion such as a ship, plane, or electron is ______
○ thermal energy
○ temperature
○ potential energy
○ kinetic energy

Explanation:

• Thermal energy is related to the internal energy due to the motion of particles within a substance, not the macroscopic motion of an object like a ship or plane.
• Temperature is a measure of the average kinetic energy of particles in a substance, not the energy of an object in motion.
• Potential energy is the energy stored in an object due to its position or state (e.g., gravitational potential energy, elastic potential energy), not due to motion.
• Kinetic energy is defined as the energy of an object in motion. The formula for kinetic energy is \(K = \frac{1}{2}mv^{2}\), where \(m\) is the mass of the object and \(v\) is its velocity. Whether it is a large - scale object like a ship or plane or a microscopic object like an electron, if it is in motion, it has kinetic energy.

Answer:

kinetic energy
