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 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: - Q:
## What is Newton's second law in terms of Atwood's machine?

A:

Full Answer >**Newton’s second law states that the force acting on an object is directly related to the acceleration.**The law is formulated as F = m x a, where F = force, a = acceleration and m = mass of the object in motion. In terms of Atwood’s machine, a force equal to the difference in the suspended weights accelerates the total mass, m1+ m2.Filed Under: - Q:
## What is rotational equilibrium?

A:

Full Answer >**Rotational equilibrium occurs when an object is either not rotating and remains at rest or is rotating at a constant rate – all torques acting on an object have a net value of zero, and there's no rotational acceleration.**This occurs due to the rotational analogue to Newton's first law: an object at rest or in motion continues in the same state unless acted on by an unbalanced torque.Filed Under:
