Question

what do you mean by acceleration?

Detailed answer needed as it's of 100 points

Answer 1

$\huge{\underline{\underline{\red{Answer}}}}$

$\bold{\boxed{\underline{\blue{Acceleration}}}}$

Acceleration of an object is defined as the rate of the change of velocity

$acceleration = \frac{change \: in \: velocity}{time \: taken}$

$\underline{\boxed{\pink{Knowledge\:Cell}}}$

$\bold{\mathfrak{\underline{\green{Unit\:of\:Acceleration}}}}$

SI UNIT is$\frac{m}{ {s}^{2} }$

CGS UNIT is$\frac{cm}{ {s}^{2} }$

$\bold{\mathfrak{\underline{\green{Positive\:Acceleration}}}}$

If the final velocity of a moving body is greater than the initial velocity then acceleration is said to be positive.

$\bold{\mathfrak{\underline{\green{Negative\:Acceleration}}}}$

If the final velocity of a moving body is less than the initial velocity then acceleration is negative. Then it's called retardation or negative acceleration.

Answer 2

Acceleration is defined as the rate of change of velocity with respect to time . Acceleration is a vector quantity as it has both magnitude as well as direction . It is also the second derivative of position with respect to time or it is a first derivative of velocity with respect to time .

The SI unit of acceleration is given as m/s² .
