ELI5: If you’re traveling at 50mph and get rear-ended by someone traveling 100mph, is it the same as someone at a standstill being rear ended by someone traveling 50mph?

The immediate crash will be substantially the same.

What happens immediately after isn’t because in the first case you’re going to be traveling at over 50mph while injured and disoriented in a vehicle that may have lost the ability to steer or brake, so are at a high risk of additional crashes and other damage.
