The terms object and instance tend to get thrown around rather loosely, and we are not going to concern ourselves with the possibly academic difference between them here. We're only interested for now in representing values. All we need to know here is that an object an instance is represented in UML and SysML by an InstanceSpecification:
We've actually already seen some instances with Slots in a previous slide, and as before, we see that the values of the Slots, which initially take any defaults defined on their corresponding value properties, can be overridden.
Under the hood the values are carried by a ValueSpecification, but in practice in the tool, if you are just dealing with numerical engineering values and strings, you don't usually have deal with that, the tool usually does a pretty good job of just letting you enter values as you'd expect.
In the tool InstanceSpecification available under the diagram sidebar menu items as 'Instance'. This power tip can save you a lot of time:
