Rotating bearings.
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
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.
True -It's "False"!
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.
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.
When a tire or anything needed to move matter requires traction.

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.
walking, braking
so you dont get tackled
