What Compare and contrast are in the three types of friction.?
The three types of friction are static friction, kinetic friction, and rolling friction. Static friction occurs when an object is at rest and prevents it from moving. Kinetic friction happens when an object is already in motion and resists its movement. Rolling friction occurs when an object rolls over a surface and experiences resistance due to deformation.
When is there friction with no movement?
Friction can occur without movement when there is static friction, which happens when two surfaces are in contact but not moving relative to each other. Static friction prevents movement from occurring until a certain force threshold is exceeded.
What happens to the force of friction as a cyclist goes faster?
As a cyclist goes faster, the force of friction remains relatively constant. The force of friction between the tires and the road depends on the coefficient of friction and the normal force, which do not change significantly with speed.
What kind of friction happens when push an object along the floor?
The friction that occurs when pushing an object along the floor is kinetic friction. This type of friction acts in the direction opposite to the motion of the object and arises due to the contact between the object and the surface it is moving on.
What happens to work done by friction if the speed doubles?
If the speed doubles, the work done by friction remains the same. Friction depends on the force between surfaces and the distance they move relative to each other, not the speed.
What happens to friction when normal reaction is increased 2 times?
The friction will also double as Friction= (friction coefficient)(normal reaction)
What happens when there is not enough friction?
no fire
What happens to the gravitational energy of a firefighter when he slides down the fire poles?
Due to friction
If normal force is dobledwhat happens to friction?
Frictional force gets doubled. But coefficient of friction does not change
What happens to things when you reduce friction?
The things will slide
What happens to friction when objects become wet?
you die
Does friction makes things cooler?
No. friction produces thermal energy therefore friction produces heat. Rub your hands together and see what happens.
What happens to a machine when it has too much friction?
The excess friction will cause the moving parts to heat up - even to becoming red hot! A cooling system: water, fans and radiator, or lubricating oil, is used to reduce the friction and so lessen the wear and tear on the moving parts.
Happens when there is not enough friction?
nothing could be held in place.
What happens to coefficient of friction when surfaces get hot?
It depends on the material.
What happens when you rub your hand together?
Friction, resulting in heat
What happens to the motion of an object when friction is involved?
Its motion slows.
