There is motion but it is non- uniform motion. It cannot be seen by us because it's motin is very slow
The work is calculated as force times distance. If the force acts constantly without there being any movement, there will therefore not be any work done.

According to Newton's First (or Second) Law, the net force must be zero in this case. Second Law: F=ma (force = mass x acceleration). If the velocity is constant, then there is no acceleration, hence, there is no force either. (It is possible that there are forces acting on the object, but the vector sum of all those forces must be zero.)
If an object is moving at a constant speed and in a straight line, then either there is
no force at all acting on the object, or else all the forces acting on it add up to zero.
The UCM (uniform circular motion) or a body moving on a frictionless surface have constant acceleration.
The object exhibits constant acceleration in the same direction as the net force.

Work is done when force is used to be approximately constant
walking
There is no force acting and therefore no work done.
The work is 20x2 = 40 Joules.
The simplest formula is: work = force x distance. This formula applies when the force is constant, and force and movement are in the same direction. Otherwise, the dot product should be used. This still assumes that the force is constant. If it isn't, an integral is used.It will be nice to use this in common. Work = Force vector . displacement vectorSO W = F s cos@Here @ is the angle between the force and displacement

For a constant force, work = force x distance. In other words, just multiply the two. The answer is in joules.
Well, if you do that for a while, you could certainly raise a sweat, and you would say that you've done a lot of work. But in the strict Physics definition of "work", none of it has been done to the object you carried. The strict definition is: Force acting through a distance. Referring to the object you carry: -- You don't move it vertically. You just hold it there against the force of gravity, but your vertical force doesn't move it up or down. So no work is done vertically. -- Horizontally, the speed is constant. No force is required to maintain a constant speed, so no work is done horizontally either.
The work is 20x2 = 40 Joules.
The idea is to multiply force times distance. This assumes that both are in the same direction, and that the force is constant. If the force is done against a gravitational field, or some other so-called "conservative force", then all the work done will be converted to potential energy. If it is done against friction, the work is basically wasted. It is converted to heat, and NOT to potential energy.
The watt is a measurement of work done by an object at constant velocity and under constant force. 1 watt, therefore, is equal to 1 Joule per second.

In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
