For the speed of an object you need to know how far it is travelling in a given time. Typically you do this by measuring the time it takes for the object to travel a set distance.
For the velocity of an object you also need to know the direction the object is travelling in.
You need the distance that something traveled in a given amount of time.
The velocity is that distance divided by the time.
v=d/t
It is a very useful number because it tells you how far something will travel in a given amount of time.
You use the equation
d=v•t Direction is also required
Velocity is speed in vector form, or speed with direction included. Speed is simply distance traveled divided by time elapsed (d/t).
Velocity = sum of initial velocity (v0) and the product of a constant acceleration (a) and the time elapsed while accelerating (t)
v = v0 + at
The displacements of the particle at different times. Velocity is the rate of change of displacement.
Distance and Time.
Speed=Distance/Time
To calculate the speed of an object, you need to know the distance traveled in meters and the time in seconds. Then simply use the formula Speed equals Distance divided by Time or S=D/T.
Two position measurements and the time between the measurements will give the average velocity (i.e. speed and direction).
Speed and Direction
well in order to calculate the speed of the object at the start point you need to know: # mass/weight of the object # the air resistance # the angle # the form of the object
To know the speed of an object we need to know the distance the object travels and the time it takes. The object's mass is not needed. Since we do no know the distance in this case, we cannot solve to find its speed.
Velocity = Delta-x / Delta-t, where x is position, t is time, and "Delta" is the "Change in" operator.Velocity is a vector, so I probably should have written x as x, or x-arrow, or some other notation to indicate it was a vector quantity, but putting an arrow hat on something is a little difficult to do here, and just making it bold is kind of subtle and could be missed.Speed is the magnitude of the velocity vector.
speed up.slow down.change shape.change direction.
To determine average speed, you need to know what distance the object traveled in meters over how long it took the object to travel that distance in seconds.
Mass speed
well in order to calculate the speed of the object at the start point you need to know: # mass/weight of the object # the air resistance # the angle # the form of the object
An object's momentum depends on its mass, its speed, and the direction it's moving. If you know these numbers, you can calculate the momentum on your own. You don't need no scientist.
If you know the speed and direction of the object's motion, then you know its velocity.
If you know the angle of the throw, and the Point where the object left your hand, you'd be able to calculate the force from how far the object Went.
To know an object's velocity, you need to know its speed and direction. You can measure speed by calculating how long an object takes to arrive at a new position. So by knowing an object's starting position, ending position, and the time it took to get there, you can calculate its average velocity. In a more advanced calculation, you could choose starting and ending positions that are extremely close to one another and calculate "instantaneous velocity." Velocity is known as a "vector value". A vector not only has a length, but a direction. In this case, "length" is the same as "speed", and direction is its change in position.
velocity of the object
object's velocity
No. For you to know acceleration you need the rate of change of speed and the direction.
You haven't given us any information from which to calculate that speed. As far as we know from the question, the object isn't moving at all.
The magnitude and direction of the object's velocity vector.
You don't convert units of length to units of time; those two are utterly incompatible.If an object moves at a certain speed, you can use the formula distance = speed x time, to relate the three. If you know two of these three pieces of information, you can calculate the third.You don't convert units of length to units of time; those two are utterly incompatible.If an object moves at a certain speed, you can use the formula distance = speed x time, to relate the three.
