What stress occurs when forces act to stretch an object?
tension
What is the The theory of tension?
Stress that occurs when forces act to stretch an object.
Describe two types of stress that deform rocks?
Compression (that acts to decrease an objects volume by squashing it together), Tension (which acts to increase an objects volume by pulling it apart) and a bonus Shear which acts in opposite directions on opposite sides of an object to make the two halves slide past each other.
Stress that occurs when forces act to stretch an object?
The boundary between tech tonic plates that are sliding past each other horizontally
What is rock tension?
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.
What are the types of stress that occurs when an object is squeezed?
Compression
What occurs when a force causes the speed of an object to decrease?
the frictional forces increase
What is the name for when the gravitational forces for an object in space are balanced?
The object is said to be weightless. If this occurs between the earth and the moon, the point where this occurs is called the null point.
What condition that is the opposite of tension occurs when a force squeezes an object?
It is subject to compression.
What Describes forces that are equal but opposite in direction when they act on an object they cancel each other out and no change occurs in the object's motion?
Equilibrium
What happens if a balanced forces are applies to a moving object?
When balanced forces are applied to a moving object, the object likely slow and eventually stop. How quickly that occurs depends on the amount of force.
When more than one force is acting on an object what determines the motion of the object?
the net force which is the vector sum of the forces. If that sum = 0 then no motion occurs
