Which of the following sets of measurements can be used to calculate acceleration?
change in time, initial velocity and final velocity
How does the initial velocity change with he point of released of inclined plane?
the INITIAL velocity does not change. It is constant. however, the velocity changes depends on the friction and inclination of the inclined plane.
What would be true of the values for initial velocity and final velocity if the acceleration were zero?
A change in velocity can be effected only by acceleration. Therefore, if the acceleration is zero, there is no change, so final velocity equals initial velocity.
If a car is traveling westward with a constant velocity of 20 meters per second what is the net force acting on the car?
well as we know that velocity is a vector hence it has magnitude as well as direction. Let us assign sign conventions for direction of velocities in this example: Let eastward velocity be positive and westward be taken as negative. Initial Velocity:-20 Final Velocity:+5 CHange in velocity=Final velocity-Initial Valocity Change in Velocity=5-(-20)=25m/s So change in velocity will be 25m/s
What is the equation for change in acceleration?
accelaration is defined as the rate of change of velocity. Therefore the formula for acceleration is a =(Final Velocity - Initial Velocity) divide by the (change in time)

How do you calculate an objects acceleration?
Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)
When calculating acceleration to find the change in velocity do you subtract the initial velocity from the final velocity?
Yes.
What is the equation for change in acceleration?
accelaration is defined as the rate of change of velocity. Therefore the formula for acceleration is a =(Final Velocity - Initial Velocity) divide by the (change in time)
What equals acceleration x time?
It's equal to the change in velocity (final velocity - initial 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.
Average velocity always equals one-half the sum of the initial and final velocities?
Is this a question? or a statement that you are unsure of? Well anyways, this would be correct if acceleration was a constant but if acceleration is not a constant, the (not-constant) acceleration would change the rate of velocity and thus that statement/question would be false.
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
