Question

1. choose the best answer. which force causes objects that are in contact with one another to resist motion? friction newtons mechanical energy gravitational force

Explanation:

Friction is a force that opposes the relative motion between two surfaces in contact. Newtons are a unit of force, not a type of force. Mechanical energy is the sum of kinetic and potential energy. Gravitational force is the force of attraction between two masses, not specifically about resisting motion between in - contact objects.

Answer:

friction
