Detailed Solution
Download Solution PDFThe correct answer is Frictional force
Key Points
- Frictional force is a contact force that acts between two surfaces in contact with each other.
- It resists the relative motion or tendency of such motion of two surfaces in contact.
- This force is only present when there is physical contact between the objects.
- Other forces like gravitational, electrostatic, and magnetic can act at a distance without direct contact.
Additional Information
- Gravitational force is a non-contact force that acts between two masses over a distance.
- Electrostatic force is a non-contact force that acts between charged particles over a distance.
- Magnetic force is a non-contact force that acts between magnetic poles or currents over a distance.
- Contact forces like friction require physical interaction between objects, while non-contact forces can act through space without direct physical contact.
