Forces in Springs
Key point
- A pulled string will develop tension –> bring the string back its original length
When a spring is pulled (increase in length), then a tension will develop.
- The tension develops because it wants to bring the string back to its original position
- Tension is opposite to the direction the string is pulled towards
Not in Formula Booklet but important
Hooke’s Law
- Tension is the opposite of displacement
- T = tension
- k = spring constant
- x = displacement
