gravity and moons forces pulls it up
gravity
The form of "a 7lb rock" in 100 years varies according to reactions: - Chemical Reactions: - chemical properties of the rock(i.e: includes salt), - the behaviour of the medium it is kept(i.e: humid or dry environment, solvent materials), - Physical Reactions: - External forces applied to the rock(i.e: acceleration), - Inertial forces of the rock. (i.e: surface tension).
Gravity and air resistance.
The three types of stresses are compression, tension and shear...
If you sit on a rock with a downward force of 'W' pounds, then the rock exerts an upward force of 'W' pounds on your derriere. We know that the sum of the forces on the seat of your pants must be zero. Otherwise the pants would be accelerating, either up or down.
Normal Fault
a result of compression forces acting on plates is massive folding and faulting of rock
that they are greater than the forces keeping the rock from moving...
When several people push on a large rock and it starts to roll, it means that the force applied by the people was greater than the force of friction holding the rock in place. This causes the rock to overcome static friction and start moving due to the net force acting on it. Once in motion, the force of kinetic friction will act to oppose the motion of the rock.
Rock tension is stress that occurs when forces act to stretch an object. Tension occurs at divergent play boundaries, when two tectonic plates pull away from each other.
dont be lazy and keep looking
If the rock is in a river it gets smoothed. Those would be the forces of gravity and self weight as well as in-situ stresses which may cause compression, tension or shear.
gravity its always acting on you
You know that the combined force is enough to overcome the force of friction.
Ice and rock
The forces that causes rock layers to move are; 1. Tensional Force. 2. Compressional Force. 3. Quiescent Force.
The duration of Tension at Table Rock is 1.55 hours.
