Question

Hassan does an experiment to find the maximum friction force between a wooden and different surfaces.

a) Name that apparatus he uses to measure the friction force

b) Hassan repeated the measurements for each surface three times. Explain why.

c) Calculate the average (mean) friction force for the glass experiment.

Answer 1

Answer:

Explanation:

Question:-

Hassan does an experiment to find the maximum friction force between a wooden and different surfaces.  a) Name that apparatus he uses to measure the friction force.

The instrument which is used to measure force of friction is Tribometer.

b) Hassan repeated the measurements for each surface three times. Explain why?

This is because:-

• Friction is the force of Resistance.
• hence, different surfaces have different tendencies of friction.
• To obtain maximum friction, we need a very rough surface.
• Hence, we repeatedly need to check the surfaces.

c) Calculate the average (mean) friction force for the glass experiment.

Lack of Data;

In this question, there must be some value provided to calculate the mean friction.

What does friction depend on?

• Force applied by the body
• Nature of the surface $.$
