Velocity is a vectorial quantity, speed with a direction.
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
Speed is the rate at which an object moves, while velocity is the rate at which an object changes its position. Acceleration, on the other hand, is the rate at which an object changes its velocity. Speed and velocity are scalar quantities, while acceleration is a vector quantity.
The units are the same (metres per second) except that the velocity also has the direction of motion associated with it.
It doesn't make sense to compare a scalar quantity (such as speed) with a vector quantity (such as velocity). Therefore you can't say that they "are the same" or "are not the same". If the velocity is constrained to be along the x-axis, for example, then specifying the speed (-10 m/s) will also specify the velocity (-10 m/s x-direction).
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.
Velocity is speed and direction
Velocity is speed with a direction
It is the speed or velocity at a particular instant.
Speed is a scalar, velocity is a vector. In other words, when the direction of the speed is relevant, it is called a velocity.
