If a helicopter descends at a rate of 8 feet per second what is the speed and velocity?

When you talk about speed, the direction is irrelevant (scalar quantity); when you talk about velocity, the direction is of interest (vector quantity). Therefore, the speed is 8 ft/sec., and the velocity is 8 ft/second in a downward direction.

What is the velocity of a helicopter traveling 6 feet per second?
Its speed is 6 feet per second. Its velocity is 6 feet per second in whatever direction it's going.
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity During this 5 second interval her acceleration will?
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
Difference with speed and velocity?
Speed rate of change on position (meter per second{m/s}) Velocity speed with direction
What is the SI unit for speed and velocity?
The SI unit for speed and velocity are the same: meter per second (m/s)
Why is it measured in meters per second?
Velocity(speed).
What is the deffinition of velocity?
Velocity is the speed of an object in a given direction. It is typically measured in meters/second.
What is the metric unit that a wave's velocity is measued in?
The speed of anything is measured in metres per second. The difference between speed and velocity is that velocity is a vector, that is it has direction and well as magnitude. So velocity would be measured in metres per second in a certain direction.
When is meters per second used?
When you want to describe a speed or a velocity.
Is meters per second a way to express units in velocity?
No, velocity is a vector, not a scalar. Metres per second is a way to express speed but to express velocity you also need a direction.
Is feet per second the same thing as velocity?
Feet per second is a unit of velocity, but not necessarily the same thing. Velocity could be in meters per hour or feet per second could be a measure of speed, which does not take direction into account, as velocity does.
What are the contents of speed?
Speed or velocity can be measured in a number of units. Miles per hour, feet per second, metre per second.
Can speed and velocity be unequal in a body?
Speed and velocity cannot be unequal for the same object. Speed tells you how quickly something is moving (as measured, for example, in meters per second) and velocity tells you how quickly something is moving and in what direction it is moving.
