Do you think that using a sneaker with a small amount of mass in it is a fair test of the friction of the sneakers?
NO
What kinds of substance reduce friction?
Friction is the act of one surface rubbing against another. To reduce friction, use something that offers a small amount of friction. Smoother substances reduce friction. A way to reduce friction is to use something which offers a small amount of friction. For example, you could use something like plastic or glass. Water, most liquids and different types of oil reduce friction. Powder, oil and grease are used in between surfaces to also reduce friction.
What is static friction in sliding friction?

What surface uses the least amount of friction?
wet surfaces like tiles have the least amount oof friction
What are the factors that determine the amount of friction between two surfaces?
Friction= Normal force* Coefficient of friction

NO
Does the ramp surface effect the speed of a car?
yes, of course different surface different amount of friction
Compare the total amount of energy before and after physical and chemical changes?
Physical Change-- Same amount of energy, but in different form Chemical Change-- Different amount of energy, and in a different form

The amount of friction divided by the weight of an object forms a unitless number called the ... of friction?
coefficientThe amount of friction divided by the weight of an object forms a dimensionless number called the coefficient of friction.

Why would it be a bad idea to measure and compare the weights of the doughs?
because there is a different amount of air in them.
What surface uses the least amount of friction?
wet surfaces like tiles have the least amount oof friction
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.
What are the factors that determine the amount of friction between two surfaces?
Friction= Normal force* Coefficient of friction
What can effect the amount of frictions between two objects?
The two factors are the coeffiecient of friction, and the 'normal' force, which is equal and opposite to the weight of the object. The coefficient of friction is diffeerent for different objects. Friction force = Coeff. X Normal Force
How are friction and force related?
friction increases the amount of force necessary to do work
