Question:
The ratio of static friction to dynamic friction is always:
The ratio of static friction to dynamic friction is always:
Show Hint
Static friction always exceeds dynamic friction because additional force is required to initiate movement against inertia.
Updated On: Feb 7, 2025
- Equal to one
- Less than one
- Greater than one
- Zero
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Understanding the friction types.
Static friction is the friction that needs to be overcome to start moving an object. Dynamic (or kinetic) friction is the friction encountered while the object is moving. Generally, static friction is greater than dynamic friction, meaning the ratio of static to dynamic friction is greater than one.
