force is a push or pull.

how this push or pull is equal to mass x acceleration.

one more doubt.

a ball is released from rest from the top of a building. initial velocity=0.after 1sec velocity is 9.81m/sec. so acceleration is 9.81m/sqs. so force

that caused the ball to fall from 0 to 1sec is 9.81N considering the mass to be 1kg. from 1second to 2seconds the net force is another 9.81N.

am i correct in the above statements.

Can anybody clarity on force on statics theory and the force referred in dynamics theory.
