How are friction and mass of an object related?
force of friction= coefficient of friction x force of normal force of normal is mass x whatever force that is acting on it (usually gravity)
What happened to the coefficients of friction as the weight increased?
Nothing. The coefficient of friction is constant, as it is dependent on the surfaces that are interacting. Normal force increases as an objects mass increases (Be careful with the word "weight", as it denotes the effect of gravity) in a constant gravitational field. This normal force is what causes an increase in friction.
What happened to the coefficients of friction as the weight increases?
Nothing. The coefficient of friction is constant, as it is dependent on the surfaces that are interacting. Normal force increases as an objects mass increases (Be careful with the word "weight", as it denotes the effect of gravity) in a constant gravitational field. This normal force is what causes an increase in friction.
How is force and friction related?
The Force of friction is equal to the coefficient of friction times the normal force. Since normal force is equal to mass times the acceleration of gravity (9.8 m/s2), the force of friction is directly proportional to the mass.
What force causes object to change direction?
gravity (up to down) friction
How are friction and mass of an object related?
force of friction= coefficient of friction x force of normal force of normal is mass x whatever force that is acting on it (usually gravity)
What are the three forces that are needed for walking?
Friction, Normal Force, & Gravity!

To keep a sled accelerating downhill the force of gravity must be greater than the normal force?
"friction"
What forces occur when something slides?
Sliding friction, (possibly) applied force, gravity, and normal force.
What is the main force in nature that causes water to flow?
Is it momentum friction electricity or gravity
How do friction and gravity relate?
The magnitude of friction is proportional to the magnitude of the normal force which is proportional to the magnitude of gravity(The magnitude of the normal force is indirectly proportional to the magnitude of gravity.). The magnitude of the normal force, N, compared to gravity, G, on angle z, is: N=cos(z)*G On a flat surface. N=G The coefficient of friction, whether static or kinetic, f is therefore: N=cos(z)*G*f
Is it true that a sled accelerating downhill the force of gravity must be greater than the normal force?
Not at all. The force of gravity must be greater than the friction force, but if the sled is on any kind of slope, then it doesn't matter what the normal force is.
