When does friction decrease?
Friction will decrease if the coefficient of friction decreases. This can be caused by having a smother surface up to a point. (When two surface are TOO smooth the friction actually increases due to molecular attraction.)
Does gravity increase or decrease with mass of an object?
Gravity increases with mass.
How weight can change?
As the mass of a body or things is constant , the weight only depends on the the gravity 'g'. As the gravity increases with the decrease of the hight of the mass from the centre of the earth , the mass also increases with the decrease of hight from the centre of the earth.
How does a car increases and decreases friction?
To increase friction, the car goes faster so that the air resistance becomes greater. To decrease friction the car goes slower to decrease the air resistance acting on the car. Hope that helped:)
Can speed affect friction force?
Actually, friction does depend on velocity. If you stop your car you have to ease up on the brakes as you slow down because friction increases as you slow down. This effect has been observed for objects travelling at bullet velocities. Friction decrease as speed increases.
Does mass effect friction?
mass effects friction by making the object go slower as mass increases

Gravity increases with mass.
When Knetic energy increases velocity and mass?
Decrease
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.
What happens when the temperature-of lava increases?
When the temperature of lava increases, its viscosity will decrease. Viscosity is a measure of the magnitude of internal friction of a substance.

What happens to volume if density increases?
Density = mass / volume. Therefore, if volume increases and mass doesn't change, density will obviously decrease.
What happens to the density as the volume increases?
If volume increases while mass remains the same, the density will decrease.
Can speed affect friction force?
Actually, friction does depend on velocity. If you stop your car you have to ease up on the brakes as you slow down because friction increases as you slow down. This effect has been observed for objects travelling at bullet velocities. Friction decrease as speed increases.
Does wax increase or decrease FRICTION?
Actually, waxing skis increases friction. Wax is not slippery. If you wanted less friction you could oil your skis.
