Hooke’s Law Flashcards
1
Q
What is the formula used to find an objects weight? Give units
A
Weight (N) = Mass (kg) x Gravitational field strength (10N/kg)
2
Q
What is Hooke’s Law?
A
The extension of a spring is directly proportional to the amount of force applied to it
3
Q
What is the equation for Hooke’s Law?
A
Force (N) = spring constant (N/m) x extension (m)
4
Q
What is elastic deformation?
A
An object returns to its original length after all the forces are removed.
5
Q
What is inelastic/plastic deformation?
A
If an object is overstretched, it does not return to its original length when the forces are removed
6
Q
What is the limit of proportionality?
A
The point at which an object stops obeying Hooke’s Law i.e. doesn’t go back to original length once forces on it have been removed.
