How do you find change in momentum over time given constant velocity?
Momentum = (mass) x (velocity vector).Given constant velocity, and assuming that mass doesn't change,there is no change in momentum over time.If there is any change in momentum, it can only be due to a change in mass.It would change in direct proportion to the mass, and the direction of themomentum vector would remain constant, in the direction of the velocity.
How do you calculate acceleration if only velocity is given?
Acceleration is a change in velocity over time - (change in velocity) / (time difference). So, you basically need two velocity measurements (or two assumed velocities), and the time difference between the measurements.
What are two words that describe the rate of motion of an object at a given point in time?
Velocity is the change of distance over change in time (distance/unit time) and Acceleration is the change in velocity/unit time.
What to do if the car change its velocity and the given is the acceleration?
Acceleration equals the change in velocity over a period of time. a= (Vfinal- Vinitial)/t Plug in the acceleration and other information they give you. Then solve.
How do you calculate initial velocity when given final velocity acceleration and time?
Acceleration is the rate of change of velocity per time, so to get velocity, multiply (acceleration)*(time). This will give the change in velocity over the specific amount of time. You must add the initial velocity to get the final velocity, so we have the formula: Vf = Vo + a*t, where Vo is the initial velocity. This means that you can rearrange to get Vo = Vf - a*t

How do you find force given mass and change in velocity Equations please?
There is not enough information. Force = Mass*Acceleration. Acceleration is the rate of change in velocity. This requires information on change in velocity as well as the time over which the change took place. There is no information at all on the latter.

How do you find the average speed of an item over a given time?
Average velocity is change in position (displacement) divided by the interval.

When is velocity contant?
That means that velocity doesn't change over time.
What is the change in velocity over time?
acceleration a----->velocity=acceleration x time: v=a x t
How do you calculate accelration?
change in velocity over change in time
How is position and velocity related?
Velocity is the rate of change of position over time.
What Change in position over time?
velocity
