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. More » Science Physics Motion & Mechanics

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 th... More » Science Physics Motion & Mechanics

The tangential acceleration of a body is the rate of change of the tangential component of the velocity of the body with time. For a body to have tangential acceleration, it needs to be moving in an angular path. The not... More » Science Physics Motion & Mechanics

The law of acceleration is formally referred to as Newton's Second Law of Motion and defines the rate of acceleration as a product of the force exerted on the object and the mass of the object. The rate of acceleration i... More » Science Physics Motion & Mechanics

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... More » Science Physics Motion & Mechanics

Symptoms of rear differential failure include vibrations, noises and other irregular driving characteristics, such as whirring on deceleration, whining during acceleration or rumbling at speeds over 20 miles per hour, ac... More » Vehicles Car Parts & Maintenance

Common examples of acceleration in real life are an object falling and a car speeding up to pass another car. All falling objects will accelerate under the force of gravity until they reach a terminal (maximum) velocity,... More » Science Physics Motion & Mechanics
