Question

Responses

Hector's velocity changed because his speed changed.
Hector's velocity changed because his speed changed.

Hector's velocity did not change because his speed did not change.
Hector's velocity did not change because his speed did not change.

Hector's velocity changed because his direction changed.
Hector's velocity changed because his direction changed.

Hector's velocity did not change because his direction did not change.

Answer 1

The correct response is:

Hector's velocity changed because his direction changed.

Velocity is a vector quantity, which means it has both magnitude (speed) and direction. While Hector's speed remained constant at 3 m/s, he changed direction from due south to due west, which means his velocity changed.
