Statement A:
- According to Statement A, any physical or mental activity is termed as work done in physics.
- However, this statement is not entirely accurate. In physics, work has a specific definition that is different from the common usage of the term.
- In physics, work is defined as the product of the force applied to an object and the displacement of the object in the direction of the force.
- So, while physical or mental activities may require effort or energy, they may not necessarily meet the definition of work in physics.
Statement B:
- According to Statement B, work is said to be positive when the body is displaced in the direction of the applied force.
- This statement is correct. In physics, work is considered positive when the force applied to an object and the displacement of the object are in the same direction.
- For example, if you push a box in the forward direction and it moves in the same direction, the work done on the box is positive.
- This indicates that energy is transferred to the object, resulting in its displacement in the direction of the force applied.
Conclusion:
- Based on the explanations above, Statement B is true.
- Work in physics is defined as the product of the applied force and the displacement of an object in the direction of the force.
- Positive work is done when the force and displacement are in the same direction.
- It is important to understand the precise definition of work in physics to correctly analyze and solve problems related to energy and motion.
