Which heating results from movement between two objects in contact with each other?

Frictional heating refers to the heat generated when two objects rub against each other. When surfaces come into contact and move relative to one another, the friction between them converts kinetic energy into thermal energy, which increases the temperature of the objects involved. This process is commonly seen in various scenarios, such as when brakes are applied on a vehicle, where the friction between the brake pads and the wheels generates heat to slow down the vehicle.

The other types of heating mentioned operate under different principles. Heat of solution involves the energy change when a solute dissolves in a solvent, resistance heating occurs due to electrical resistance when current flows through a conductor, and static electrical heating is related to the discharge of static electricity without physical contact, which does not involve the relative motion between objects. Therefore, frictional heating is specifically characterized by the heat generated through contact and relative movement, making it the correct answer in this context.
