|
What is weight's unit ? |
Newtons or N |
|
What is the equation for force ? |
m x a or mass times acceleration |
|
What is the unit for force ? |
Newtons or N |
|
What is the equation for spring constant ? |
-kx or spring constant x spring extension |
|
What is the unit for spring force? |
Newtons or N |
|
FUN FACT: For spring force, what is x |
x is always negative, meaning that -kx would be -k(-x), cancelling out the negative sign making it kx. |
