What causes a marble to roll?
Because of the force of friction pushing against the ball. The only way it could avoid that is if it wasn't rubbing against the ground and was instead closing floating in air, like the puck in air hockey. The air blowing up on it keeps the puck and the table from rubbing against each other and causing friction. :)
What causes the most injuries during an earthquake?
Falling and collapsing Buildings and other falling things
When friction prevents the rocks on either side of a fault from moving past each other the fault is?
Elastic
What builds up as layers of sediment pile on top of each other?
falling in water
How does radioactivity affect the planet?
Among other things, it keeps the core hot (and molten).
What keeps the plates from sliding past each other?
Friction.
What is a Force that keeps 2 object that are touching from easily sliding past each other?
None. Change your question for two OBJECTS and the answer is friction.
Do free falling objects have friction?
To be very technical and precise, the answer consists of two parts: 1). No. 2). Outside of laboratory conditions, there can be no free-falling objects on Earth. "Free falling" means that there is no other force on the object except the gravitational one, so there's no friction acting on it. But this situation is impossible on Earth, because anything that falls is falling through air, so it does have friction acting on it ... called "air resistance" ... and it's not free falling.
Two forces that affect a falling object?
Gravity is one, and I believe that friction is the other. Friction here being caused by the resistance to motion of the fluid the object is falling in. Generally this is termed air resistance or drag and it is related to the object's velocity and cross section as well as the fluid's viscosity.
Does an free falling object has an frictional effect?

What is the direction of air resistance on a falling object ?
Just like any other source of friction, air resistance effectively results in a force opposite to the object's motion. If the object is falling, then the force is upward.
Do shoes have a high or low friction?
Shoes have a higher amount of friction compared to other surfaces. If shoes did not have high friction, then people would be slipping and falling everywhere. I am sure shoe companies do not want this. But some shoes that do have low friction would be a dance shoe or bowling shoes, these are often slideing alot so they have lower amount of friction.
What keeps leaning tower from falling?
because they have led ingots counter waits and still ropes fixed to pull it the other way
How does lubicus help to reduce friction?
Lubricants reduce friction by various means. Here are some:They form a layer between surfaces that are moving with respect to each other that keeps those surface from contacting each other. The lubricant keeps the surfaces apart.The lubricant washes away particles that might cause friction between the surfaces. It acts as as cleanser.Some lubricants harden the surfaces of the parts they are lubricating to make them less subject to wear.
What made Cahokia different from other mound builder towns?
Cohokia was larger than the other mound builder towns.
What is the strongest type of friction?
There are four types of friction: Fluid Friction (The friction caused by falling through air or water, or any other liquid etc), rolling friction (Like a ball rolling across the floor), static friction (The force it takes to begin something's movement), and sliding friction(Like pushing a box across the floor). In order of strongest to weakest it's Static, Sliding, Rolling, Fluid.
When does static electricity happen?
When friction is created by two objects that are moving but not relative to each other, its called static friction. Static friction keeps an object from moving until friction is created to move it.
