A crate slides across a floor and slows down. The force acting against its motion is:
- Friction
- Fraction
- Fracture
- Frequency
Show answer and solution
Correct answer: A. Friction
1. Two surfaces are in contact and moving past each other.
2. That contact always resists the relative motion.
3. The force is friction.
