What is the formula for calculating final velocity when you know the initial speed and the acceleration?
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
What equals acceleration x time?
It's equal to the change in velocity (final velocity - initial velocity).
Why is the value of velocity equal to speed?
This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.
When is speed equal to magnitude of velocity?
Speed is equal to the magnitude of velocity almost always. Speed is total distance / total time no matter which way the distance goes. Velocity is the distance from a starting point divided by total time.
What is final speed divided by acceleration?
Final Velocity minus Initial Velocity (all together this is the change in velocity) divided by the average acceleration will give you the time it took for the object to reach that speed.(Vf - Vi) / Aaverage = Time

How do you find final speed if acceleration time and beginning velocity is given?
You can find the final speed by using the formula: final speed = initial velocity + (acceleration * time). Plug in the given values for initial velocity, acceleration, and time into the formula to calculate the final speed.
Is final velocity equal to speed tell you yes or no?
No. (We'd like to explain why, but the question doesn't permit it.)
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
If the final velocity will be less than initial velocity the object is increasing speed or decreasing speed?
If the final velocity is less than the initial velocity, the object is decreasing speed. The object has slowed down or its speed has decreased compared to when it started.
When is speed equal to the magnitude of velocity?
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
If an object comes to a stop does that mean that the final velocity is equal to zero?
Yes, if an object comes to a stop, that means its final velocity is indeed zero. This is because velocity is a vector quantity that includes both speed and direction, so if the object stops moving, its speed is zero as well as its direction.
When do speed and velocity become equal?
Speed and velocity become equal when an object is moving in a straight line without changing direction or when it is moving at a constant speed. Velocity is a vector quantity that includes both speed and direction, so if the direction of motion is constant, speed and velocity will be the same.
In the acceleration equation what do v1 and v2 represent?
v1 = initial velocity v2 = final velocity
Is acceleration equal to initial velocity minus the final velocity divided by the time?
No, It is the average velocity.
When do the velocity and speed of a moving body become equal?
The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.
A ball starts at rest accelerates uniformly and travels 250m in 5 seconds What is the final velocity and the acceleration of the ball?
The final velocity can be calculated using the formula final velocity = initial velocity + (acceleration * time). Since the ball starts at rest, the initial velocity is 0. The final velocity = 0 + (acceleration * 5). To find the acceleration, you can use the formula acceleration = (final velocity - initial velocity) / time. The final velocity is unknown, but we just calculated the final velocity is equal to 5 times the acceleration, so acceleration = (final velocity - 0) / 5. Substituting the final velocity = 5 times the acceleration into the acceleration equation, we get acceleration = (5 * acceleration - 0)/5. Solving for acceleration, we get acceleration = 1 m/s^2. The final velocity is 5 m/s.
