Rotating bearings.
What else can I help you with?
The force needed to overcome kinetic friction is usually less than that needed to overcome static friction true or false?
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
How can friction be increased in a given situation?
Friction can be increased in a given situation by increasing the roughness of the surfaces in contact, increasing the force pressing the surfaces together, or by using materials with higher coefficients of friction.
Is The force needed to overcome static friction usually less than that needed to overcome kinetic friction.?
True -It's "False"!
True or false the force needed to overcome kinetic friction is useally greater than that needed to overcome static friction?
False. The force needed to overcome static friction is typically greater than that needed to overcome kinetic friction. Static friction is the resistance to motion when an object is at rest, while kinetic friction is the resistance to motion when an object is already in motion. Static friction requires more force to overcome because it is necessary to break the initial "stickiness" between the surfaces.
What are two examples of situation where it is best to reduce friction?
It is best to reduce friction in machinery to improve efficiency and reduce wear and tear. Another situation is in sports like ice skating or skiing where reducing friction allows for smoother movement and faster speeds.
What are situation where the friction is useful?
When a tire or anything needed to move matter requires traction.
The force needed to overcome kinetic friction is usually less than that needed to overcome static friction true or false?
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.

When friction is not needed?
when machines are used

Wet pavement is more slippery than dry pavement because of force needed to overcome what friction is less than the force needed to overcome sliding friction?
On wet pavement, the presence of water reduces the friction between the tires and the road surface, making it more slippery. This is because the force needed to overcome static friction (needed to start moving) is less than the force needed to overcome sliding friction (needed to maintain motion). As a result, it is easier for a vehicle to slide or skid on wet pavement compared to dry pavement.
What are the things that really needed friction?
walking, braking
When is friction not needed in rugby?
so you dont get tackled
