Forces - Squashing And Stretching Flashcards
1
Q
Deform
A
To change shape
2
Q
Compress
A
To squash into a smaller space
3
Q
Stretch
A
An object can be stretched if you exert a force in it
4
Q
Reaction
A
- support force
- provided by a solid surface
5
Q
Extension
A
-amount by which an object can be stretched
6
Q
Tension
A
- stretching force
- stretches objects
7
Q
Elastic limit
A
-point beyond where a spring will not return to its original length when the force is removed
8
Q
Hooke’s Law
A
-states that if you double the force of an object, the extension will double as well
9
Q
How does the support force from the floor work
A
- Floor is sold so it has closely bonded particles
- weight will compress the bonds and the bonds become even tighter
- they push back on you and support the weight
10
Q
Hooke’s law detail and formula
A
- graph of force against extension is linear
- not all objects obey this law
- F=kx F=force. K=spring constant. X=extension
