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.
Learn MoreDeceleration is synonymous with slowing down or is related to the relative directions of velocity and acceleration. The meaning of the word in common language differs from its meaning in physics.
Full Answer >Rate of deceleration is expressed as negative acceleration. The negative sign indicates that deceleration takes place in the opposite direction as acceleration. Both are as expressed in standard units m/s^2.
Full Answer >There is no such thing as an antigravity room, because it is impossible to completely eliminate gravity. However, NASA has several means of creating a microgravity, or extremely low gravity environment, including drop towers, a special aircraft flying in parabolic arcs and water tanks in which people are given weights to make them neutrally buoyant.
Full Answer >There are three types of acceleration in general: absolute acceleration, negative acceleration and acceleration due to change in direction. Acceleration is defined as the rate of change of velocity.
