Friction force (f) is the normal force by the surface on the object multiplied by the coefficient of friction.

What types of materials can cause friction?
Any type of material has friction because everything has microscopic hills and valleys; some materials have more friction because the materials hills and valleys are larger than other materials.
How do mass and surface type affect friction?
if the mass is more than the friction is high. and if the surface is rough then also the friction is more. thus we can say that both mass and surface type affects friction.
How does mass effect efficiency?
The mass affects the efficiency of an object. It adds more weight, which causes more friction. More friction=less efficiency
How surface influences the amount of friction there is?
The larger the contact surface, the more friction. The more uneven the surface, the more friction. The material of the surface has also an effect on friction.
Why do surfaces that are rough produce more friction?
On rougher surfaces, the surface area is usually larger, meaning there is more to rub against therefore more friction is produced.

How does the mass an object affect it acceleration?
When an object is falling in a gravity field, its mass does not affect its acceleration. If under the influence of friction then it takes more energy to accelerate it the larger mass it has, here on Earth. The larger the mass the more potential it has to do work if it is above the surface of the earth than a smaller mass. But in turn, to get it to the higher point more work must be done for a larger mass than a smaller mass.

The more mass an object has the harder it is to change its acceleration?
Because of air friction, the more physical space that an object takes up, the more power the object will need to move, this is because of the way air forces friction onto the moving object, therefore a small car/vehicle will have less air friction than a larger vehicle with more surface area
What is high air resistance?
Air resistance is a friction force, the flow of air over a surface will cause friction and produce drag. Thanks
Why the mass of an object has an effect on speed when moving on a road?
because the more heavy it is, the more friction it has on a road. the friction slows it down.
The larger the mass the inertia?
Inertia is directly related to mass. More mass means more inertia.
Why do surfaces that are rough produce more friction?
On rougher surfaces, the surface area is usually larger, meaning there is more to rub against therefore more friction is produced.
The more of what object has the more force it takes to move it?
You increase the object's acceleration.
Does friction cause you to use more energy?
Yes, usually.
