Even though no physical work is done on the wall, your muscles are still contracting and using energy to generate force. This sustained muscular effort causes fatigue and leads to a feeling of tiredness, despite the lack of movement in the wall.
That's correct. Work is only done when a force causes an object to move in the direction of the force, so pushing against a stationary object, like a wall, does not result in any work being done.
Pushing against a stationary wall is an example where a force is exerted on the wall, but no work is done on the wall since it does not move. Work is only done when a force causes an object to move over a distance in the direction of the force.
No, pushing against a wall does not result in any work being done. Work is only done when a force causes an object to move in the direction of the force, so if the wall does not move, no work is done.
Some examples of situations where no work is done include holding a book in a stationary position, pushing against a wall that does not move, and carrying a backpack while standing still. In these cases, although there may be physical effort involved, no work is being done because there is no displacement of an object in the direction of the force applied.
An example that is NOT a product of work is maintaining a constant velocity while pushing against a stationary wall. Work is only done when a force causes a displacement, and in this case, the wall does not move even though a force is applied against it.

An example of an action that does no work would be pushing on a stationary wall. Despite applying force to the wall, since the wall does not move, no work is done as defined in physics (work = force applied * distance moved in the direction of the force).
The work done in physics is defined as the force applied to an object times the distance over which that force is applied. When rolling a bowling ball, if it is simply pushed against a tree without moving, no work is done because there is no displacement. In contrast, kicking a football typically involves applying force to the ball and causing it to move, resulting in positive work being done as the distance traveled by the ball is significant. Therefore, kicking a football generally involves more work than pushing a bowling ball against a stationary tree.
Physically pushing against a wall can be considered as doing work in a physics context, as work is defined as the force applied over a distance. The force you exert on the wall does not result in any displacement of the wall, but work is still being done in the physics sense, as long as the force is being applied.
Work is only accomplished when a force results in the movement of an object in the direction of the force. If the force is applied but there is no displacement of the object, then no work is done. For example, pushing against a stationary wall does not result in any work being done because the wall does not move.
Yes, pushing against a brick wall would require force and displacement, which are the two components of work. You would be exerting energy to apply a force on the wall, but if the wall doesn't move, there would be no work done on the wall.
No work is done when pushing on a wall because work is defined as force applied over a distance in the direction of the force. When pushing on a wall, the wall does not move, so there is no displacement in the direction of the force, hence no work is done.
In activity B, where you are pushing against a rock but not moving it, work is being done in its scientific meaning as the force you apply results in a displacement over time, even though the rock doesn't move. In activities A and C, no work is being done because there is either no displacement in the case of sitting still on a rock (A) or no force causing a displacement in the case of pushing a rock over a cliff (C).
