Elastic Flashcards
1
Q
What is the def for elastic
A
Objects that can return back to their original state after a force has been removed
2
Q
What is extension
A
It is a measurement of how much an object has stretched compared to its original length
3
Q
What is directly proportional
A
Force = extension, straight line, both connected
4
Q
What is the equation for elastic potential energy
A
1/2 x spring constant x (extension)²
5
Q
Define the Specific heat capacity of an object
A
The amount of energy needed to raise the temp of 1 kg of a substance by 1 degrees
6
Q
What is spring constant
A
Basically stiffness
7
Q
How can you measure elasticity
A
Hang weights off a spring, should be a directly proportional graph
8
Q
What is a moment
A
It is a tuning force (Like a spanner)
