A: ### Quick Answer

**There is no such thing as a formula for deceleration; there is only a formula for acceleration.** To find the acceleration, subtract the initial velocity from the final velocity and divide that sum by the time taken. If that formula yields a negative answer, it indicates a negative acceleration, or deceleration.

There are many other formulas related to acceleration in physics. To find the distance traveled, assuming initial velocity, acceleration and time taken are given, the initial velocity can be multiplied by time. That sum can then be added to half of the acceleration multiplied by time squared. There are other more complex formulas that exist, such as the five formulas for constant acceleration. These formulas are designed to describe the motion of a particle that is in a state of constant acceleration.

- Q:
## What is the difference between acceleration and deceleration?

A:

Full Answer >**Acceleration refers to the change in velocity of a moving object within a certain period of time, either to a slower or faster pace, while deceleration exclusively refers to the negative acceleration (or slowing down) of an object.**In layman's terms, acceleration usually only refers to positive acceleration.Filed Under: - Q:
## What is the formula used to calculate mass?

A:

Full Answer >**There are two formulas that may be used to calculate mass: mass is equal to the volume of an object multiplied by its density (m=v*d) and mass is equivalent to an object's weight divided by the acceleration of gravity (m=w/g).**The appropriate formula depends on the available variables.Filed Under: - Q:
## What is the definition of constant acceleration?

A:

Full Answer >**Constant acceleration is a change in velocity that doesn't vary over a given length of time.**If a car increases its velocity by 20 mph over the course of a minute, then increases by another 20 mph the next minute, its average acceleration is a constant 20 mph per minute.Filed Under: - Q:
## What is the formula to calculate force?

A:

Full Answer >**For an object with unchanging mass, force equals mass times acceleration.**This is abbreviated as f = ma. Force is a push/pull on an object resulting from interactions with another object. Having a magnitude and a direction makes force a vector quantity.Filed Under:
