If you are using a linear spring, then the only field you need to set is the spring constant. This says how hard the spring reacts when you displace it farther. The higher the constant, the higher the reaction.
If you are using a linear damper, then you need to set a damping constant. Unlike the spring, the faster the masses go, the harder the damper reacts. This type of component should be used to represent losses, such as friction.
If you are using a non-linear spring or damper, then type in an equation that describes the force reaction. You may use "d" (displacement), "v" (velocity), pi, and e
