What else can I help you with?
The mechanical advantage of a machine without friciton is called the machine's mechanical advantage?

Why does a football bend?
Friciton slows down the spin of the ball. In order to conserve angular momentum, the ball begins to move in an arc of decreasing radius.
How does friction apply to the real world?
because two things rubbing against each other causes it. that means the real world have to deisqin the cars or machine differntly to eliminate friciton. also oil redices it
How do lubricants help to reduce friciton?
The molecules of lubricants can slide over each other due to the weak attractions between them and hence they allow the machine parts to slide over each other smoothly reducing friction and damage.
Are skis a machine?
No simply an invention. There are no moving parts (other than locking the boots into the skiis) or complicated pieces that move automatically once some work is inatiated. They take advantage of phycis in that they reduce the friciton between you and the snow. The time it takes to get down a hill can also be calculated given distance, angle, acceleration...

How did the sun become a big star?
First off, the Sun is not a big star. It is a Main Sequence star, which means it's an average size star. Second, at the formation of your Solar System, gravity caused rocks to start getting closer together and spinning. Eventually, the friciton and gravity was so great, and became so hot, the spinning rocks became a star, known as the Sun.
Does friction have any role to play in snow clad areas?
As snow becomes hard and packed it can be very slippery. The coefficent of friciton is then less then when the tires are on pavement which means that the "sticky" force is not as great holding the tires and the snow covered road together. In these conditions the car tires begin to slip as they try to grip onto the road but the static frictional force to get the car going is not there and as a result the car tires spin in the snow.
Of the two forms of friction which is generally the hardest to overcome?
Friction depends on the roughness of the surface between the objects, it also depends on the area in contact between the objects. Athletes can have spikes on their shoes to maximise friction with the ground.
How does kinetic friction apply to the real world?
Kinetic friction is the force that resists the motion of objects sliding against each other. It is encountered in everyday scenarios like when we walk on the ground, drive a car, or rub our hands together. Understanding and managing kinetic friction is important for designing efficient systems and reducing wear and tear on moving parts.
The pull of the engine is 5000 N When the wagon's speed is increasing how large is the friction force?
The question does not have enough information for a single answer. All we can tell from the question as is is that the friciton force must be less than 5000N. To give a definite number to the magnitude of the friction force we need to know at what rate the wagon is accelerating when the pull is 5000N.
