At which stage is potential energy at its minimum?
The potential energy due to gravity is at a minimum, since the mass is lifted the least amount above ground. In fact, if ground level is imagined at the bottom of the motion, the potential energy due to gravity is zero at this point of the motion.
At what position is the potential energy maximum?
vertical position
Which position has the least potential energy?
position B
Where is the most potential energy of a pendulum?
What do you think happens to the energy of a ball in a pendulum that swings back and forth? The ball at the top of the swing is briefly motionless. It has the greatest potential energy, because it is highest above the surface.
How do we use energy in our daily lives?
When we talk about residential uses of energy, these are the most basic uses of energy. They include watching television, washing clothes, heating and lighting the home, taking a shower, working from home on your laptop or computer, running appliances and cooking.
Why is energy an essential part of human life?
Answer: Energy is essential to life and all living organisms. The sun, directly or indirectly, is the source of all the energy available on Earth. We need energy to complete the regular body requirements to digest our food , to breathe,to move,to run , to travel and continue the metabolism of our regular life.

Why do we need energy in simple words?
Energy fuels your body’s internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world. Water, your body’s most important nutrient, helps facilitate the chemical reactions that produce energy from food.
Where do we use energy?
We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy.
Where do we obtain energy from?
For photosynthetic cells, the main energy source is the sun. Cells, like humans, cannot generate energy without locating a source in their environment. However, whereas humans search for substances like fossil fuels to power their homes and businesses, cells seek their energy in the form of food molecules or sunlight.
