Question

what is acceleration for class 9​

Answer 1

Answer:

accelerate means speed

Answer 2

Answer:

ACCELERATION can be defined as rate of change of velocity with respect to time

. S.I unit of acceleration is meter per second square

. IT is measured using a device called as accelerometer

. IT IS A VECTOR quantity

. Acceleration Occurs mainly due to change in speed

. acceleration can also be described into different type

. acceleration is mainly dependent on speed

Explanation:

here is a small trick which will help you know the relationship between speed velocity and acceleration

. First comes the speed

. second comes the velocity

. third comes the acceleration

IN SIMPLE FORM.

s, V =ds/dt ,a=dv/dt=ds/dt

here s is speed v is velocity and a is acceleration
