What is the direction of average acceleration?

Average acceleration points in the same direction as the change in velocity over time. If the velocity is increasing, the average acceleration will be in the same direction as the velocity. If the velocity is decreasing, the average acceleration will be in the opposite direction.


An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?

The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.


What is the physical meaning of a negative average velocity?

A negative average velocity indicates that an object is moving in the opposite direction of the chosen positive direction. For example, a negative average velocity would mean the object is moving left if the positive direction is considered right.


Compare and contrast acceleration and velocity?

-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.


How velocity different from speed?

Velocity is acceleration and direction put together. The velocity of something changes if either acceleration or direction changes. Speed is just the average MPH measure. Velocity is not acceleration and direction put together. In that kind of description, velocity is is speed and direction put together. Velocity is a vector, whose size is the speed.

What is the formula of velocity?

There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.

What measures the rate of change in velocity?

Police measur speed with a radar gun. It uses the Doppler effect to find speed. You can measure distance traveled and use a stopwatch to measure speed yourself. You asked about velocity, however. Velocity is the combination of speed and direction. To measure velocity, you have to track the direction of travel. For that, either a compass, a chart or some other measure.


How is velocity different from average speeed?

Velocity is speed and its direction. Average velocity is average speed and its direction.


Which term explains wheather an objects velocity has increased or decreased over time?

Acceleration (a=v/t where a=acceleration, v=velocity and t=time; or Average acceleration= Δv/Δt, where Δv is the change in velocity and Δt is the change in time) shows the rate of change in velocity over time.If Acceleration (a) is positive, it means that velocity has increased over time and if it is negative, it implies the velocity has decreased over time [also commonly known as deceleration(-a)]


How is it possible for a car to have an average velocity of zero and an average speed of 65 mph?

If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.


Find average acceleration and instanious acceleration?

average acceleration is the average of the acceleration of a body in its entire motion where as instantaneous acceleration is the rate of change of velocity at an instant. it may be a function of time or velocity or displacement.


Can calculate average acceleration of an obj ect given change in velocity with respect to time?

Yes, you can calculate average acceleration by dividing the change in velocity of the object by the time taken for that change to occur. The formula for average acceleration is (final velocity - initial velocity) / time. This calculation gives you the average rate at which the velocity of the object is changing over a specific time interval.
