no speed cant be negative
No, speed of a object cannot be negative. Speed is a restricted quantity in physics because it only tells how fast something is going; such quantities are called scalars. Velocity on the other hand, can be negative, because it tells the direction as well as the amount of speed; it belongs to a class of objects called vectors. Formally, speed is the absolute value of velocity.

Speed of a particle cannot be negative as it is a scalar quantity. It has only magnitude associated with it .It only tells how fast something is moving. On the other hand, velocity of a particle can be negative as it has both magnitude as well as direction associated with it. It tells how fast something is moving as well as in which direction something is moving.
The positive and negative signs are indicators of direction.
