what is defination of accelaration?

Answer 1

Acceleration is the rate of change of velocity(speed)

Answer 2

In physics, acceleration (symbol: a) is defined as the rate of change (or time derivative) of velocity. It is thus a vector quantity with dimension length/time². In SI units, this is metre/second².

Answer 3

Acceleration is any change in velocity divided by the time during which the change takes place. Change in velocity can be either a change in speed or a change in direction.

Answer 4

In classical mechanics acceleration is defined either by as the time-derivate of velocity, or as force divided by the mass of the object.

a=dv/dt

a=F/m

Answer 5

Acceleration is measured as a change in rate of velocity. It is measured usually in meters/second/second. So if you were going 10 meters/second and 2 seconds later you were going 20 meters/second your acceleration over that span would be 5 meters/second/second.

hope that helps

cheers,

Answer 6

let D=distance =f(x) let v= velocity=g(x) and let a=acceleration=h(x) the acceleration is defined as so

d/dx*D=V the rate of change in distance is velocity
d/dx*V=A the rate of change in velocity is acceleration

Answer 7

gainig speed while while traveling. to get from 60 to 70 you have to accelerate. when you get to 70 & stay there u are no longer accelerating. if u slow down to 60, u are decelerating. when u get to 60 & stay at 60, u are no longer decelerating.

Answer 8

acceleration is any change in velocity or direction. deceleration is simply a colloquialism arbitrarily assigned as is deescalate.

Answer 9

acceleration is increase in speed. if a wheel is goiung at constant it mean its not accelerating

Answer 10

rate of change of velocity
