(any unit of length) / (any unit of time)
is a unit that can be used for the magnitude (size) of velocity, and must always
be accompanied by a description of direction. Without it, all you have is a speed,
not a velocity.
The SI unit is meters/second, but any length unit divided by any time unit may be used, for example kilometers per hour, cm/minute, AU/week, etc.
The SI unit is meters/second, but you can use any other combination of distance / time.
Usually, the units for speed and velocity are derived as units of length, divided by units of time. For example, the SI unit for speed - the unit most commonly used by scientists - is meters/second, though units of kilometers per hour are more common among non-scientists. Any unit of length can be divided by any unit of time. There are also units that are not explicitly derived from units of length and time - for example knots, and fractions of "c" (the speed of light).
Velocity may be expressed in which of the following units:
C.) meters per second
meters per second.
"8 seconds" is not a velocity.
160 feet per second
.13m
A ball thrown vertically upward returns to the starting point in 8 seconds.-- Its velocity was upward for 4 seconds and downward for the other 4 seconds.-- Its velocity was zero at the turning point, exactly 4 seconds after leaving the hand.-- During the first 4 seconds, gravitational acceleration reduced the magnitude of its upward velocity by(9.8 meters/second2) x (4 seconds) = 39.2 meters per second-- So that had to be the magnitude of its initial upward velocity.
The only equation that comes to mind is the one for impulse. An impulse is a force applied for a limited time. > Velocity change = (force * time) / mass > Example : A 10 kg mass is travelling at 100 m/s, a force of 100 newtons is applied for 5 seconds in the same direction as the motion, calculate the new velocity. > Velocity change = (100 * 5) / 10 = 50 metres per second Add to original velocity = 100 + 50 = 150 metres per second
25 N acting on 10 kg increases the velocity by 25/10 metres per second, every second, so after 3 seconds the speed is 7.5 metres per second.
Velocity increases after 5 seconds
Newtons (second) and most powerful law, force(f) = mass(m) * acceleration(a)and its derivatives, deal with the changes on a body when forces are applied to it.Example: impulse - velocity changeA force of 1000 newtons is applied to a mass of 100 kilograms for 10 seconds,calculate the velocity change(vc).f = m * a , but a = velocity change(vc) / time(t),so:f = m * (vc / t)so:vc = (f * t) / mso:vc = (1000 * 10) / 100vc = 100 metres per second
Velocity is derived by dividing displacement with time in seconds
Time is universally measured in seconds. Velocity can be measured to whatever is practical, whether it be miles per hour or metres per second. Velocity also has a direction in the label. Work is the measure of the amount of energy transferred by a force. Measured in joules. Speed is the same as velocity, minus the direction. Force is measured in Newtons.

The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
"8 seconds" is not a velocity.
The duration of WWE Velocity is 2760.0 seconds.
0.0002315 m/s OR 0.0008333 km/hour The velocity of an object is the rate of its change in position in a certain direction. Velocity is a vector quantity; this means that it has both a magnitude and direction. To find the average velocity of an object in motion, the following equation is used: average velocity= (total displacement)/ (total time elapsed) The SI units of velocity are "m/s" , but any distance unit over any time unit is also acceptable. Solving for the velocity asked for: First let's change hours to seconds: (12 hours ) x (6o minutes/hour )x (60 seconds/minute)= 43200 seconds Finding the velocity: average velocity= (displacement)/ (time)= 10m/ 43200 seconds= 0.000231481 m/s
which power of a telescope might be expressed as "0.5 seconds of arc"?
Assuming - without any justification - that the sprinter starts from a standstill, it is 333.33...(repeating) newtons.
