Final answer:
A stationary metal sphere can have kinetic energy if it is struck by an external force, causing it to move. The amount of kinetic energy will depend on the mass and velocity of the moving sphere.
Step-by-step explanation:
A stationary metal sphere can have kinetic energy if it is struck by an external force, causing it to move. Kinetic energy is the energy of motion, and it depends on the mass and velocity of an object. Even though the metal sphere is initially at rest, when it starts moving, it will gain kinetic energy.
For example, if a person kicks a stationary metal sphere, the sphere will start moving and gain kinetic energy. The amount of kinetic energy will depend on the mass of the sphere and its velocity.
Therefore, even though a metal sphere may be stationary, it can still have kinetic energy when it is in motion.
