Speed is the magnitude of velocity (which has a direction as well).
Velocity consists of a speed and a direction. If any of the two changes, the velocity changes.
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
speed cannot as it is just a magnitude, however as velocity relates both magnitude and direction, and direction can be negative, technically you can have a negative velocity.
No. Velocity consists of a magnitude and a direction. The magnitude of velocity is called "speed", and that's what the speedometer measures. But it displays no information concerning the direction in which the car is moving.
Velocity is a vector quantity, which means that a body's speed and direction are both required to define it. They are different because: Speed is the rate of change of distance with time but velocity is the rate of change of displacement with time.

Speed and velocity are similar in terms of the rate at which an object is moving, commonly expressed in terms such as miles per hour (mph) or feet per second (fps). Velocity differs from speed because velocity also deals with direction, specifically with respect to a point of origin.
Not necessarily. Velocity is made up of speed and direction, so if they go in different directions, their velocity won't be the same.
they are different words with the same meaning.

Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
speed cannot as it is just a magnitude, however as velocity relates both magnitude and direction, and direction can be negative, technically you can have a negative velocity.
No. (We'd like to explain why, but the question doesn't permit it.)
