Question

Once the applied force exceeds the limiting force of friction and the object begins to move, which type of friction takes over?

Options

• Static friction continues to act

• Limiting friction acts

• Kinetic friction takes over

• Friction becomes zero

Answer 1

Kinetic friction takes over

Explanation:

When the applied force exceeds FL (the maximum static friction), the object starts to slide, and static friction is replaced by kinetic friction. Kinetic friction acts while the object is in motion and is generally lower than the limiting static friction.
