What else can I help you with?
When a force is exerted on an object work is done only if the objec?
moves in the direction of the force. If the object does not move in the direction of the force, then no work is done on the object.
Is work done every time forces are exerted on an object?
No, work is only done if the force causes the object to move in the direction of the force. If the force is exerted but the object does not move, no work is done. Work is calculated as force multiplied by the distance the object moves in the direction of the force.
What is an example in which a force is exerted on an object without doing work on the object?
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.
Can an object exert a force on itself, and if so, how does this self-exerted force impact the object's motion or stability?
No, an object cannot exert a force on itself. The concept of self-exerted force is not supported by the laws of physics. Objects can only experience forces from external sources, which can impact their motion or stability.
How work force and distance related?
Work = force x distance traveled (only when the force and distance are acting in the same direction)

What is the only condition that work is done?
Work is done when a force is applied to an object and the object moves in the direction of the force. If there is no movement, no work is done, even if a force is applied.
Work is done when only what is applied?
Work is done when a force is applied to an object and the object moves in the direction of the force. It is calculated by multiplying the force applied by the distance the object moves in the direction of the force. If there is no movement, then no work is done.
Why a force acting on an object does no work if the object is not in motion?
Work is defined as the product of force and displacement. If an object is not in motion, there is no displacement, thus no work is done by the force acting on the object. Work is only done when a force causes an object to move through a distance in the direction of the force.
What is push or pull that makes an object move or puts it into motion?
A push or pull that acts on an object is a force.
What is the force exerted by the object you are trying to move?
The force exerted by an object you are trying to move is its weight, which is equal to the mass of the object multiplied by the acceleration due to gravity (9.8 m/s^2 on Earth). The force needed to move the object must be greater than or equal to its weight to overcome friction and inertia.
Why is an object considered weightless when there is no normal force or when an object is in freefall?
An object is considered weightless when there is no normal force acting on it because weight is the force exerted by gravity on an object's mass. In freefall, the object is only subject to the force of gravity, which causes it to accelerate with the same acceleration as the object itself, resulting in a sensation of weightlessness.
When does a force applied to an object not do any work?
A force does not do any work on an object when the object does not move in the direction of the force or when the force is perpendicular to the direction of motion. Work is only done when there is displacement in the direction of the force.
