Which statement is true about non-contact forces?

• A. Non-contact forces can act without touching an object
• B. Non-contact forces require contact to transfer energy
• C. Non-contact forces always act at a distance
• D. Non-contact forces only exist with magnets

Answer: (A)

Non-contact forces are forces that can act on an object without touching it. Gravity pulls objects toward each other even when there is no contact, magnets can attract or repel without touching, and electric forces act between charged objects across space. Because of this, these forces can cause motion or energy changes without any physical contact. The idea that non-contact forces require contact to transfer energy isn’t true, and they aren’t limited to magnets—gravity and electric forces are also non-contact.
