The size and shape of particles can affect internal friction by influencing how easily they can slide past each other. Smaller, round particles have less friction due to their smoother surfaces, while larger, irregular particles can create more friction as they interlock and resist movement. Different sizes and shapes of particles can result in varying degrees of internal friction within a material.
What else can I help you with?
Does sand increases friction?
Sand can increase friction between surfaces, as the rough and irregular shape of sand particles can create more contact points with the surfaces in contact. This increased contact results in more resistance to sliding or movement, thus increasing friction.
Do most of the particles in a football move in one direction?
Yes, when a football is kicked, most of the particles inside the football will move in the direction of the kick due to the force applied. However, there will also be some particles that move in other directions due to the irregular shape and the internal pressure of the football.
How does changing the shape of an object affect the friction and air resistance?
Changing the shape of an object can affect friction and air resistance. For friction, the surface area in contact with another surface can increase or decrease, altering the friction force. For air resistance, a more streamlined shape will experience less resistance compared to a less streamlined shape due to differences in how air flows around the object.
What is the grinding down of a surface surface due to the friction caused by contact?
That is called abrasion, where the surface is worn down by repeated friction and rubbing from contact with another material. This process can lead to the removal of small particles from the surface, causing it to become smoother or change in shape over time.
What kind of shape volume and particles solid have?
solid have definite shape , definite volume and close together particles
How are internal friction and the size and shape of particles related?
yes
How shape of stone aggregate effect the concrete?
the general sense of friction can be used for answering this since angular particles have more friction in between them as compared to regular stone particles they hold together better
What is the angle of friction of silica sand?
The angle of friction for silica sand can vary based on factors such as grain size, shape, and moisture content. Typically, the angle of internal friction for silica sand falls within the range of 30-35 degrees.
Does sand increases friction?
Sand can increase friction between surfaces, as the rough and irregular shape of sand particles can create more contact points with the surfaces in contact. This increased contact results in more resistance to sliding or movement, thus increasing friction.
What compound will have the subatomic particles so closely related that they take on a ridgid shape?
Neutronium. The substance of a Neutron star.
Why does a heap of sand have a pyramidal shape?
If you drop small particles like sand they roll and form a natural angle. (Just steep enough to be held by friction.) Further particles keep rolling and the angle stays the same. This makes the natural shape.
How does shape effect viscosity?
The shape of particles in a fluid can affect the viscosity by influencing how they interact with each other. Irregular shapes can cause more resistance to flow compared to spherical or uniform shapes, as they may create more friction or turbulence. In general, particles with irregular shapes tend to increase viscosity by disrupting the flow of the fluid.
Do most of the particles in a football move in one direction?
Yes, when a football is kicked, most of the particles inside the football will move in the direction of the kick due to the force applied. However, there will also be some particles that move in other directions due to the irregular shape and the internal pressure of the football.
How are the particles in a liquid different from the particles in a solid?
a gas have no definite shape so the particles can move around freely but in a liquid ,which has a definite shape, particles move around but are restricted
