That's right, but be sure to read the question carefully. They are probably asking for the work done by the push (not the work done by all forces). If so, the weight is irrelevant regardless of how it moves.kaweezah said:so if the displacement is downward i use the weight and if it's horizontal i use the push. am i getting the idea correctly?
Work done is defined as the product of the force applied to an object and the displacement of that object in the direction of the force. It is a measure of energy transfer and is expressed in joules (J).
Work done is directly related to both weight and push. Weight is the force of gravity acting on an object and push is the force applied to an object. Both weight and push contribute to the overall force acting on an object, which determines the amount of work done.
No, work done is not necessarily the same for weight and push. This is because weight is a constant force, while push can vary in magnitude and direction. Therefore, the displacement of an object may differ depending on whether it is being pushed or pulled, resulting in a different amount of work done.
The angle of push does affect the amount of work done. The force applied in the direction of displacement (parallel to the displacement) contributes to the work done, while the force applied perpendicular to the displacement does not contribute to work done. Therefore, the greater the angle between the direction of push and the direction of displacement, the less work is done.
No, the amount of work done cannot be determined without knowing the weight and push. Both of these factors are necessary in calculating the overall force acting on an object, which is essential in determining the amount of work done. Without this information, the work done cannot be accurately calculated.
