How do you think the mass of an object affects how much friction get exerted on the object by a rough surface?

Physics

Shkiper50 [21]3 years ago
7 0

Explanation:

Friction can't affect mass of a substance(considering for a substance whose mass doesn't change with time),rather it is the mass of an object which can affect friction variously. Let's take some example to understand the situation. So,higher the mass of the object,higher will be the frictional force.

Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

The ways farmer or rancher should keep healthy herd or flock healthy are:

  1. Always keep a hygienic environment that is cleaned daily.
  2. Do make sure that there one is following the right stocking density.
  3. Do Clean and also disinfect areas of the house that is contaminated.
  4. Daily try and empty and also clean the feeders and water troughs.
  5. Do stop or avoid carrying or bringing in new disease by using biosecurity measures.
  6. Do hinder animals getting sick by trying to optimize husbandry and management on the farm.
  7. Create a kind of health plan for the animals with your vet where there is a vaccination protocols when necessary.
  8. Always engage in constant animal disease testing.
  9. Observe, diagnose and treat any sick or infected animals in the right way.
  10. Do Isolate or remove infected and sick animals from the group of animals.

A birdcage with mass 22.5kg at rest on a living room floor is acted on by a net horizontal force of
patriot [66]

m = mass of the birdcage = 22.5 kg

F = net force acting on birdcage to move it = 140 N

a = acceleration produced due to the force applied

a)

Using newton's second law

a = F/m

inserting the values

a = 140/22.5

a = 6.22 m/s²


b)

t = time of travel of crate = 10.5 s

v₀ = initial velocity of the crate = 0 m/s

X = displacement of the crate

displacement of the crate is given as

X = v₀ t + (0.5) a t²

X = 0 (10.5) + (0.5) (6.22) (10.5)²

X = 342.88 m
