An example of intentionally increasing friction?

Answers

Answer 1

Answer: When a car gets stuck in a marshy pond, we place a wooden block so that the friction increases and the car is helped out of the marsh. In this situation, we intentionally increased friction. Of course there are many other such examples. Hope that helped.

Answer 2

Answer: You can increase friction intentionally by rubbing two objects together.

How does mass effect the speed of a forced object

Answers

Answer:

the bigger the mass, the smaller the acceleration and the smaller speed

Explanation:

this can be proven from the formula F = ma

F = m×speed/time

Or a practical example is that of a heavy object and a light object if pushed with the same force, it'll be observed that the small object moves faster or with a greater speed than the heavy object

How is amplitude related to loudness

Answers

The loudness of a sound is linked to the size of the vibration which produces it. A big vibration makes a louder sound. Scientists use the word 'amplitude' for the size of waves. For waves on water, it is easy to measure the amplitude.
