2.Write the causes of friction.
3.Why sportsmen use shoes with spikes?
please help me to complete this question is very urgent I have to complete please don't send unwanted any messages if you don't know please don't give me any message I will mark as brainliest who give me the correct answer

Answer:
Spikes increase the surface of the shoes & make it rough which results in an increase in friction. This helps to have more grip on the floor and chances to slip reduces. This makes it easy for sportsmen to walk or run as their grip on the ground increases.
1. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
2. Causes of Friction: Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations.
3. Spikes increase the surface of the shoes & make it rough which results in an increase in friction. This helps to have more grip on the floor and chances to slip reduces. This makes it easy for sportsmen to walk or run as their grip on the ground increases.
