The ratio between the force causing a body to slide along a plane and the force normal to the plane is called __________________?
Correct answer: C. Coefficient of friction
- A. Coefficient of resistance
- B. Coefficient of internal friction
- C. Coefficient of friction
- D. All are correct
Explanation
The coefficient of friction is the ratio of the tangential force needed to cause sliding to the normal force pressing the surfaces together. It is commonly expressed as frictional force divided by normal force.
