What is the term which means to change speed?

Acceleration or deceleration


Is deceleration and retardation same?

"Deceleration" is a decrease in speed, however you are still going in the SAME direction so it is POSITIVE. "Retardation" is going in the OPPOSITE direction, therefore it is NEGATIVE.


How do you measure or calculate deceleration during a collision?

In a controlled test condition (like crash tests on cars) an accelerometer is used to measure the rate of deceleration. It should be possible to estimate the deceleration following a collision if the speed of the vehicles at the moment of the collision is known. We could do this by measuring the amount the car was crushed/dented during the collision. We know the vehicle decelerated from its starting speed over this distance so we can estimate the average deceleration. I believe there are more sophisticated techniques used by accident investigators. As an aside, in strict physics terminology, slowing down (as well as any other change in velocity) is acceleration, not deceleration however deceleration is often used to imply a reduction in speed in every day English. If you want to get into this further have a look at "Are speed and velocity the same?" and remember that acceleration is also a vector.


What does a flat line represent on a speed time graph?

Motion at a constant speed - no acceleration or deceleration.


Is it true that a negative acceleration always means that a moving object is decelerating?

Yes. That is what the term deceleration means.

Is deceleration a form acceleration?

Acceleration and deceleration are both the rate at which velocity changes, Deceleration is a negative acceleration. In an equation the rate of deceleration is shown as a negative acceleration valueCentripetal acceleration is different and represents the rate of change of tangential velocity. There is no equivalent centripetal deceleration.


What is the abbreviation for deceleration?

The abbreviation for deceleration is decel. Another common abbreviation for deceleration is dec. There is not a standard abbreviation in place for deceleration.


What the definition of deceleration?

The definition for deceleration is: a decrease in rate of change; for example: "The deceleration of the arms race."


What came first the deceleration of independence or the constitution?

deceleration of independence


What is rate of deceleration?

The rate of deceleration is how quickly something is slowing down.


What is the definition of deceleration acceleration?

Acceleration is when speed increases. Deceleration is when speed decreases.


Why do scientist often refer to deceleration as negative acceleration?

Deceleration is often referred to negative acceleration because deceleration is not AA commonly used word.


How are deceleration and acceleration related?

Acceleration and deceleration are related by their their sign. Acceleration is positive ( increase in velocity with time) and deceleration is negative (decrease in velocity with time).


What is the meaning and formula for deceleration?

Deceleration is the rate of decrease of velocity with respect to time. It is the negative of acceleration. The formula for deceleration is the same as that of acceleration, only that the acceleration is represented as negative. The formula is: - (deceleration) = (final velocity) - (initial velocity) time Therefore, (deceleration) = (initial velocity) - (final velocity) time


What is deceleration uniformly accelerated?

It would be acceleration or deceleration, depending on whether the acceleration is greater than the deceleration or vice versa. dvA/dt = acceleration -dvD/dt = deceleration If you accelerate an object being decelerated, then the act is ( dvA - dvD )/dt
