Question

what is connected motion??

Answer 1

When the motion of one body is directly connected to the motion of another body then these bodies are said to be under connected motion.

Answer 2

here is ur answer.....
when two bodies are connected to each other and move together or move in a connected way then the motion is known as connected motion... it's in a no. of things like
between a string and a pulley .
MOTION OF TWO BODIES CONNECTED BY A STRING OVER A PULLEY



Motion of Two Bodies Connected by a String over a pulley on different planes.

Consider a light inextensible string passing over a smooth pulley, , so that the tension (T) in both the strings is same. 

Let mass m1 is greater than mass m2. Since the string is inextensible, the upward acceleration of mass m2 will be equal to the downward acceleration of mass m1. This acceleration is given by

and tension in the string,

Let us now consider the following cases of motion of two bodies connected by a string.

1. First of all, let us consider the motion of two bodies connected by an inextensible string, one of which is hanging freely and the other is lying on a smooth horizontal plane

Since the string is inextensible, the tension (T) in both the strings will be equal . The acceleration of the system
and

2. If instead of smooth plane, it is a rough horizontal plane,
will act in the opposite direction to the motion of mass m2, where u is the coefficient of friction.
3. When the plane is a smooth inclined plane
4. When the plane is a rough inclined plane
hope it helps uhhhhh...
