Forces and Elasticity Flashcards
1
Q
Can an object be compressed if only one force is acting on it?
A
No, when only one force acts on an object it will accelerate and move. Two forces are required to keep it still so it can be deformed.

Q
What is missing from this equation for the elastic potential energy in a spring?
elastic potential energy = 0.5 x (extension)². Give the full name, not the symbol.
A
Spring constant, the full equation is elastic potential energy = 0.5 × spring constant × (extension)2.
