How do you find velocity with a known time and distance?
Velocity equal distance divided by time. For example, an object that traveled 5 metes in 10 seconds had a velocity of 5/10 meters per second which is .5 meters per second. Velocity is speed in a direction. Sometimes a navigate or positive number is sufficient as the direction. Other times you will need to be more specific, such as .5 meters per second East or 1.3 meters per second 30 degrees East of North.
What is the centripetal acceleration of an object being swung on a string with a radius of 5 meters at a velocity of 4 meters a second?
Use the formula a = v2 / r, with v = velocity (speed, actually) in meters/second, r = radius in meters. The answer will be in meters per square second.
Is there a difference between meters per second and meters?
Yes. The first is a speed (or velocity), the second is a distance.
What is the acceleration of a car that moves at a constant velocity of 20 meters per second?
-- "Acceleration" is any change of velocity.-- "Velocity" is a speed and its direction.-- "20 meters per second" is a speed, not a velocity, because it doesn't mention a direction.-- We don't have enough information to say anything about that car's acceleration.If, for example, it happens to be moving at a constant speed of 20 meters per secondon a circular track, then it has plenty of acceleration.
You throw a ball straight up with a velocity of 40 meters per second What is the ball's velocity after 5 seconds?
it is 10 meters per second straight down
What is an example of velocity?
5 meters per second down
What is acceleration and its si unit?
Acceleration is the rate of change of velocity - how fast a velocity changes. Therefore, its units are naturally (meters/second) / second, usually written as meters/second2.Acceleration is the rate of change of velocity - how fast a velocity changes.

Which is a unit for velocity?
The SI units for velocity, as well as speed, are meters/second. But actually, you can divide any distance by any speed - for example, kilometers / hour is commonly used in practice (for example, that's what a car's speedometer reads), instead of meters/second.
What is S.i unit for wave velocity?
The SI unit for wave velocity is meters per second (m/s).

What is the velocity when falling 1000 meters?
Ther velocity when falling 1000 meters is v=sqroot(2x1000x9.8) = 140 meters/second.
What is the SI unit for Final Velocity?
The SI unit for final velocity is meters per second (m/s).

Use the formula a = v2 / r, with v = velocity (speed, actually) in meters/second, r = radius in meters. The answer will be in meters per square second.
What is mks unit of velocity?
The MKS (meter-kilogram-second) unit of velocity is meters per second (m/s). It represents the distance traveled in meters per unit of time in seconds.
Is there a difference between meters per second and meters?
Yes. The first is a speed (or velocity), the second is a distance.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
Why is it measured in meters per second?
Velocity(speed).
