If you mean "acceleration", that is the rate of change of velocity - how quickly velocity changes. For example, if an object falls down without air resistance, close to Earth's surface, its speed will increase by 9.8 meters per second every second. This is commonly written as 9.8 meters/second2 - and this rate of change of velocity is called "acceleration".
In physics, acceleration is a rate of change in velocity. Acceleration can also be used to describe a rate of change of anything, chemical or physical, such as reaction time, aging, growth, absorption, dissolution, etc.
An Acceleration is the change in speed or direction.
The rate of change of velocity is called accelaration.
If u is the intial velocity, v is the final velocity in time interval t then,
a=change in velocity/time
a=v-u/t
Acceleraton is the rate at which velocity changes as time progresses.
"Acceleration" = the rate of change of velocity, and the direction of the change.
Acceleration is the rate of change of velocity, in symbols, dv/dt. In simple terms, "how fast the velocity changes".
About 9.8 meters per second squared (m/s2) downwards.
Acceleration is the rate of change in velocity (speed) Thus if your speed is constant (50 miles per hour) your acceleration is zero
height=acceletation(t^2) + velocity(t) + initial height take (T final - T initial) /2 and place it in for time and there you go
Check for a serious exhaust leak if this sound occurs on rapid acceletation. Squealing also occurs in power steering if it is low on fluid and you are cornering. Another squeal is a slipping fan belt ... get it checked out soon as it will only get worse and probably cost more later for repairs than for a simpler repair right now.
