Two objects can have the same speed but different velocities because velocity is a vector quantity, while speed is a scalar quantity. Here's how:

* Speed: Only considers how fast an object is moving. It's a magnitude without direction.

* Velocity: Considers both how fast an object is moving *and* the direction it's traveling in. It's a magnitude with a direction.

Example:

Imagine two cars:

* Car A: Travels east at 60 mph.

* Car B: Travels west at 60 mph.

Both cars have the same speed (60 mph). However, they have different velocities because they are moving in opposite directions.

Key Points:

* Velocity can be positive or negative depending on the direction of motion.

* A change in direction *always* results in a change in velocity, even if the speed remains constant.
