Question
An object needs to overcome which friction force in order to start its movement?
- Static friction
- Sliding friction
- Rolling friction
- Fluid friction
Hint:
Static friction is a frictional force that must be overcome for something to get going.
The correct answer is: Static friction
An object needs to overcome static friction force in order to start its movement.
- Static friction holds an object at rest and prevents from moving.
- It limits the magnitude of an applied external force.
- Thus, the static friction has to be removed from the object in order to move it.
