How does a surface affect friction?
Depending on the roughness or smoothness of the surface, it will increase friction if it is rough,(which has more microscopic hills and valleys). If the surface is made of a smooth material, it will decrease friction
How does air resistance act as a form of friction?
When consider the micro scale. Pusing a mass need force and air has mass. Object travel through air would push and drag air along with it and so the conservation of momentum would made the object slow down because it speed air up. The object shape also affect the amount of air push, more surface contact with air is more friction and smoother the surface would less dragging air along with it and is lesser friction.
Why surface of electric machine are made smooth?
The surface of electric machine are smooth why
What are some forces that might affect a rock as it tumbles down a hill?
A force hit the rock which made it roll down the hill.
Why is the true surface of a mirror invisible?
That's because it is made of glass, with a silver coating on the far surface.
What does mass have to do with force?
force (F) is equal to mass (m) multiplied by acceleration (a). F=m*a. if mass is made subject, m=F/a. hence mass is directly proportional to force. therefore an increase( or decrease) in force means an increase ( or decrease) in force also.

What is the difference between cross filing and draw filing?
Cross filling is made across the surface to be filed from tip to handle, which gives a smoother cut. Draw filling on the other hand, is done across the surface by moving from one edge of the file to the other.
How does friction decrease the acceleration of a car?
friction decreases the acceleration of a car by creating a greater force which pushes against the acceleration force. the friction is a force, but more of it means that whatever is pushing against it ( acceleration in this case) is made smaller.
What does a meteor make when it hits earth?
If it's big enough, a crater.Crater:A bowl-shaped depression in a surface made by an explosion or the impact of a body, such as a meteoroid.ORA large indention in the surface of the ground made by the force of something.
Can the suspension on a Cadillac XLR be changed so that it rides smoother?
yes but has to be custom made for your car
Why is a trumpet made of metal?
it is smoother than plastic and travels the wind faster i think
Why aren't mirrors white?
For it to be considered a mirror, the surface must be smooth compared to the wavelength of light. Certainly smoother than a quarter of a wavelength.Whilst white reflects all colours, no restriction is made on the surface smoothness.A common mirror one meets is inside a prism, (e.g. inside prismatic binoculars) but these surfaces have no colour at all.
Why is the angle of contact of mercury obtuse?
Cohesive force between molecules of mercury is more than adhesive force between molecules of mercury and those of glass. This results in formation of a convex meniscus for surface of mercury. Actually, cohesive and adhesive forces are phenomenon due to surface tension of a liqud. The angle made by mercury from the glass surface is obtuse.

Why were Apollo Astronauts floating on the surface of the moon?
They were just moon walking. Due to decreased gravitational force it made it look like they were floating at times.
