What are four factors that can affect the amount of friction between two objects
umka2103 [35]
As the Force of friction is equal to F _{f} =µF_{n} by using the Law of Action Reaction; as the force normal is the conterforce of gravity

F _{f} =µF_{n}
F_{f}=µF_{n}

Therefore, by looking at the equation we can infer that

The force of friction is directly proportional to the mass, gravitational constant, and the co-efficent of friction

Because the gravitational constant is dependant on gravitation, a planet's mass and radius also affect the force of friction

But DO NOTE:
That the co-effecient of friction is only applicable between two rubbing surfaces and unaffected by gravitational constants.

The inclined plane in the figure above has two sections of equal length and different roughness. The dashed line shows where sec
saveliy_v [14]

The static friction exerted on the block by the incline is \mu _ s _1 Mgcos \ \theta.

The given parameters;

  • <em>mass of the block, = M</em>
  • <em>coefficient of static friction in section 1, = </em>\mu_s_1<em />
  • <em>angle of inclination of the plane, = θ</em>

<em />

The normal force on the block is calculated as follows;

Fₙ = Mgcosθ

The static friction exerted on the block by the incline is calculated as follows;

F_s = \mu_s F_n\\\\F_s = \mu _s_1(Mg cos\ \theta)\\\\F_s = \mu _s_1 Mgcos\ \theta

Thus, the static friction exerted on the block by the incline is \mu _ s _1 Mgcos \ \theta

Determine the value of the force exerted by the surface (normal force) on a
Advocard [28]

Answer:

53.5 N

Explanation:

Vertical component of the F force   50 sin30    = 25 N  upward

   force of gravity = m g = 8 * 9.81 =78.5 N Downward

NET downward force by block on table = net upward force exerted by table =  78.5 -25 =53.5 N
