The Sentence: “Energy has the same unit as that of work.”
Answer: True
Explanation:
In physics, energy and work are closely related concepts, and they indeed share the same unit of measurement. Here’s a detailed explanation:
- Definition of Energy and Work:
- Energy: Energy is defined as the capacity to do work. It exists in various forms, including kinetic energy, potential energy, thermal energy, etc.
- Work: Work is done when a force is applied to an object, causing it to move in the direction of the force. Mathematically, work is defined as the product of the force and the displacement of the object in the direction of the force.
- Unit of Measurement:
- In the International System of Units (SI), the unit of energy is the Joule (J).
- Similarly, the unit of work is also the Joule (J).
- One Joule is defined as the amount of work done when a force of one newton moves an object one meter in the direction of the force.
- Recent Examples:
- Electric Vehicles (EVs): In the context of electric vehicles, energy consumption is often measured in kilowatt-hours (kWh), but when converted to work done, it is ultimately expressed in Joules. For instance, an EV battery with a capacity of 50 kWh can be understood as having the capability to perform a certain amount of work, which can be quantified in Joules.
- Renewable Energy: In the field of renewable energy, such as wind or solar power, the energy produced is quantified in Joules. For example, the energy output of a solar panel over a day might be given in kilojoules (kJ), which is a unit of energy and can also be used to express the work done by the panel in generating electricity.
Conclusion: Energy and work are essentially different aspects of the same physical quantity, and their unit of measurement, the Joule, reflects this equivalence. Therefore, the statement that “Energy has the same unit as that of work” is true.

A newborn child needs the first milk given by a woman’s breast, which is called colostrum. Colostrum is the first secretion that comes out from the mother’s breast soon after delivery of the baby. All foods eaten require nutrient dense food and contains antibodies and antixodants which are vital for the formation of a newborn baby’s immune system. It turns to the breast milk after the day of birth of your baby up to 2-4 days of your baby’s age. Colostrum is thicker and more yellow than the breast milk that is given to the baby subsequently.
See lessBreastfeeding the baby in the first hour of childbirth enhances the good effects in multiple ways:
1. At this point initial milk is colostrum which boosts the immunity of your child in the shortest time possible.
2. Reduces the likelihood of your child getting diseases such as sepsis, pneumonia and diarrhoea.
3. Naturally warms your baby up post delivery and helps shield them from hypothermia.
4. Promotes well-being and can help control your baby’s pulse and breathing.
5. Reduces lifetime susceptibility of different diseases
6. It promotes skin-to-skin contact between the mother and the baby so that the baby can easily pick good bacteria from the mother skin, and the temperature is well controlled.
7. It also assists boost the affection which exists between the mother and the child and makes the chances of being able to breast feed your child very high.
