Questions and Answers
What is static friction?
What is static friction?
- Occurs when solid surfaces slide over each other
- When a force is applied to an object but it does not cause it to move (correct)
- Occurs when an object moves through a fluid
- Occurs when an object rolls over another
What is fluid friction?
What is fluid friction?
Occurs when an object moves through a fluid, meaning either a liquid or gas.

Study Notes
Types of Friction
-
Static Friction
- Prevents motion between two surfaces that are at rest.
- Requires a force to be applied, but the object does not move.
- Common example includes pushing against a stationary wall.
-
Fluid Friction
- Occurs when an object moves through a fluid, which includes both liquids and gases.
- The resistance experienced by objects such as a skydiver in air or a swimmer in water.
- Influenced by the speed of the object and the viscosity of the fluid.
-
Sliding Friction
- Takes place when two solid surfaces slide past each other.
- Often leads to wear and tear on surfaces due to direct contact.
- A practical example is slipping and falling on pavement.
-
Rolling Friction
- Arises when an object rolls over a surface.
- Generally less than sliding friction due to reduced contact area.
- Examples include riding a motorcycle or pushing a ball along the ground.
