# What 2 things determine the friction between to objects?

Friction between two objects depends on the static coefficient of friction (if the object is currently not moving) and the normal force from the surface, acting in the direction opposite the direction of gravity. Wiki User

Because Ffric = Normal force * coefficient of friction, and Fnormal = mass*9.81m/s^2, the coefficient of friction for those 2 objects, which represents the relationship between their touching surfaces, and the objects masses, are the two things that determine frictional force. As you probably can tell, the higher a coefficient of friction, the harder it is to move an object. Higher masses also increase the difficulty of moving an object because it results in a higher frictional force.   Earn +20 pts

### How does friction move things?

Friction does not move things. Friction is the force that opposes motion between two objects that are touching. Not enough friction allows for things to move, depending on what kind of friction; the less force it has.

### What 2 things determine the strength of gravity between 2 objects?

The mass of the objects and the distance between them.

### What are 3 things that friction can do between two objects?

Heat,wear,and static electricity(depending on what the objects are made of).

### What two things affect the amount of friction between two objects?

The coefficiant of friction between the two surfaces and the normal reaction force of the object lying on the surface

### How does friction affect objects and how can they be changed?

Friction makes things warmer and can be changed by lubricants

### What 2 things determine the force of gravity between 2 objects?

-- the product of their weights -- the distance between their centers

weight and mass

### Amount of friction depend on two thing?

The amount of friction between two surfaces depends on more than two things. It could depend on many things like The shared surafce area The amount of force between the objects How rough or somooth the surfaces are The presence of a lubricant or glue Ball bearings Even temperature. Many things affect the amount of friction between things

### What things in the house need the most and less friction?

things with wheels such as glass, bowls and other circular objects

### How do you find heat from friction?

When you rub two things together, the friction between the two things will produce heat.
