Question

Force that acts between two sticks when they are rubbed together

Answer 1

The force that acts between two sticks when they are rubbed together is friction.

Step-by-step explanation:

Friction is a fundamental force that opposes the relative motion or tendency of such motion between two surfaces in contact. When sticks are rubbed together, the force of friction comes into play. This force is caused by the irregularities on the surfaces of the sticks, as microscopic bumps and ridges interlock, creating resistance to sliding motion.

The mathematical expression for frictional force
`(\(F_f\))` can be represented by the equation:

`\[ F_f = \mu * N \]`

Here,
`\(μ\)` is the coefficient of friction, and
`\(N\)` is the normal force, which is the force exerted by a surface perpendicular to the direction of motion. The coefficient of friction depends on the nature of the materials in contact.

Understanding friction is crucial in various fields, from physics and engineering to everyday activities. In the context of rubbing sticks together, friction generates heat, making it a vital factor in activities such as starting a fire.
