A schoolbag is any bag for carrying school things. It can be different types of bag, like a bag you carry on your back (a rucksack or backpack), or a bag that hangs from your shoulder (a satchel).
A rucksack can be for any purpose, not just for carrying school things.
So, a rucksack is also a schoolbag if you use it to carry your school things.
Hi O'Prata,
There are a couple of differences.
So, a rucksack is also a schoolbag if you use it to carry your school things.
Does that make sense?

Hi Vanessa Suzuki,
Rucksack and backpack are two names for the same thing. You can use either one :)
