Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
In physics, the combination is called VELOCITY.
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
Velocity measures the speed of an object in a specific direction. Unlike speed, velocity is a vector quantity that takes into account both the object's speed and the direction it is moving.

Speed in a given direction is velocity.
SPEED has the speed only; while VELOCITY has the direction and the speed.
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
Speed in a given direction is called velocity.
Speed is a scalar, velocity is a vector. In other words, when the direction of the speed is relevant, it is called a velocity.
Velocity is speed and direction
Velocity is speed with a direction
It is the speed or velocity at a particular instant.
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
