Contact force is another name for _________.
Both 1 and 3
The correct answer is Both 1 and 3, i.e. friction and muscular force.
A contact force acts only when two objects are in direct physical contact. Friction acts at the contact surface opposing relative motion, and muscular force is exerted by muscles pushing or pulling an object they touch — both require contact.
Magnetic force, by contrast, can act at a distance without contact (a non-contact force), so option 2 is excluded.
