The force from the string on the block is not necessarily equal to your force on the block.mr newtein said:two blocks are connected by string if i pull a block,then block(it will transmit force) will also pull string then,string will also pull block (a& r pairs)forces on block are by me and by string of equal magnitude than why is block accelerating
jedishrfu said:common layman's usage is:
I apply a force on a block and it moves.
but for physics you need to think this way:
I apply a force (f=ma) on a block of mass m and it accelerates (no friction case).
in the real world with friction:
I apply a force (f=ma) on a block of mass m and it accelerates to some constant
speed because the frictional force increases with increasing speed and opposes the
force I am applying.

A force in mechanics is a push or pull on an object that can cause it to accelerate or change its motion.
The common types of forces in mechanics include gravity, friction, tension, normal force, and applied force.
Forces can either cause an object to start moving, stop moving, or change its direction and speed.
Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on an object. Mass does not change, but an object's weight can vary depending on the strength of gravity.
The net force on an object is calculated by adding all the individual forces acting on the object in the same direction and subtracting the forces acting in the opposite direction.
