Speed is scalar quantity and velocity is a vector - velocity has both speed AND direction
(You might say that velocity is speed with an attitude!)
velocity is measured in relation to a certain spot on earth or a space, whether its moving or not. Speed is measured in relation to the earth.
Velocity . . . what speed and direction something is moving. Acceleration . . . how fast the speed and/or direction of its motion are changing.
speed is scalar while velocity is a vector. In other words, velocity is to do with direction also. Speed does not show direction.
Velocity is speed plus its direction. -- "30 mph" is a speed. -- "30 mph north" is a velocity. -- "30 mph east" and "30 mph south" are the same speed but different velocities.
Velocity is a vector Speed is a scaler
SPEED has the speed only; while VELOCITY has the direction and the speed.
Velocity is speed with direction
velocity is speed with direction; velocity is a vector and speed is a scalar
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.
Speed is magnitude of velocity, also velocity possess direction.
they are different words with the same meaning.
Velocity is speed and its direction. Average velocity is average speed and its direction.
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
