Is it possible to have a coefficient of kinetic friction that is more than 1?
True -It's "False"!
How do laws of motion affect your ability to control your vehicle?
The lower the dynamic coefficient of friction between your tires and whatever you are driving on, the more likely you are to continue moving in a straight line at a constant speed, despite your efforts to turn or brake.
Does friction affect stopping distance?
Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
What is the difference between static friction and sliding friction?
Sliding friction is always less than the static friction by small amount.
How does friction change the energy in a machine?
Well i think friction and air resistance cause some of the mechanical energy of an object to change to thermal energy so the mechanical energy of the object is not destroyed. Rather, it is transformed into thermal energy. the total amount of energy always stays the same. <3 Tayler

What is slididng friction?
Static friction is the side force between objects that needs to be overcome to move it; sliding friction is the side force between objects that needs to be overcome to keep it moving once it starts to move, and is generally lower than static frictionmove it
What is friction acting on objects that are not moving?
Friction is holding immobile objects in place.
Is it possible to have a coefficient of kinetic friction that is more than 1?
True -It's "False"!
A lower coefficient of friction indicates that the two surfaces in contact have less resistance?
Yes but make sure you are clear in your understanding between the coefficient of friction and the force of friction. The force of friction is the force that resists the motion of two surfaces moving against one another. The amount of friction is determined by the product of the coefficient of friction and the normal (perpendicular) force that is pressing the two surfaces together. The coefficient of friction is a unit-less constant, that indicates how two surfaces compare to two other surfaces that are being pressed together the same amount. If the normal force is the same on two pairs of surfaces the pair of surfaces with the lowest coefficient of friction will experience the lower force of friction.

Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
What happens when two blocks are on top of each other and allowed to slide down a plane at a constant acceleration?
It depends on the masses of the blocks and the coefficients of friction. If the force of friction between the lower block and the ramp is greater than the force of friction between the upper and lower blocks, the upper one will accelerate at a greater rate than the lower one, and it will fall off. Otherwise, they will accelerate together.
Why is the mechanical efficiency of most compound machines lower than most simple machines?
It is lower because compound machines have more moving parts that a simple machine does.
What is the difference between static friction and sliding friction?
Sliding friction is always less than the static friction by small amount.
How is kinetic friction a negative and positive thing on a car or moving object?
In a car Friction creates Energy losses that result is a loss of mechanical efficiency, and therefore lower gas mileage. On the positive side friction in the Braking System transform energy of motion into HEAT, allowing the car to stop.
