by itself it is speed; if associated with a direction it is velocity
It describes 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 is measured in m/s. Velocity is measured in m/s IN A SPECIFIC DIRECTION. You may be driving at 4 mph north, or at 5 mph at 330˚, and your velocity in the northern direction will still be 4 mph. In this example, your speed is different, but your velocity is the same. Thus even if speed remains constant, but its direction changes, your velocity will be different.
No. Velocity states both speed and direction.Time gets involved in calculating the speed.
Velocity is a speed and its direction. -- "30 miles per hour" is a speed -- "30 miles per hour north" is a velocity -- "30 mph north" and "30 mph east" are equal speeds but different velocities.
speed and 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.
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.
Velocity includes the information on what direction the speed is pointing. 60 mph north and 50 mph north are different velocities. 60 mph north and 60 mph west are also different velocities. Speed doesn't care what direction it's going. 60 mph north and 60 mph west are the same speed. 60 mph 50 mph are different speeds.
Speed is measured in m/s. Velocity is measured in m/s IN A SPECIFIC DIRECTION. You may be driving at 4 mph north, or at 5 mph at 330˚, and your velocity in the northern direction will still be 4 mph. In this example, your speed is different, but your velocity is the same. Thus even if speed remains constant, but its direction changes, your velocity will be different.
Velocity means speed or speediness. When you drive a car at 55 mph, that would be it's velocity. It does have an upper limit of velocity. It can also mean the rate of change in speed. You can also look at it as the speed that gets you get up to 55 mph.
speed
Speed is how fast you are going.Velocity is almost the same but for one thing: it also includes what direction you are moving.For example:A car can have a speed of 50 mph, but a velocity of 30 mph northwards.
610 mph in the NorthWest direction. Both speed and direction are required to specify the velocity.
"Mph," or miles per hour, is used to measure speed or velocity.
Velocity is a vector quantity that measures speed (and also includes direction). 55 mph is a speed. 55mph North is a velocity.
No. Velocity states both speed and direction.Time gets involved in calculating the speed.
their average speed is greater than their average velocity.
