What forces cause acceleration?
A layman's attempt: Any unbalanced force applied over time to an object that is free to move will bring about acceleration.
Which best describes a similarity between power plants that use water as an energy source and those that use wind as an energy source?
"Free fuel" They both utilize solar energy.
Energy conservation during free-fall?
potential energy = mass*acceleration due to grav*height=kinetic energy at any point + total energy dispersed as you move through the air (air resistance)
How is the acceleration of an object in free-fall related to the acceleration due to gravity?
The acceleration in free fall IS the acceleration due to gravity, since "free fall" is the assumption that no forces other than gravity act on the object.
What is the acceleration of an object moving upward?
On earth, the vertical acceleration of any object that's free to move vertically,and has no artificial force imposed on it, is 9.8 meters (32.2 feet) per second2,directed downward. The source of the acceleration is the mutual gravitationalattraction between the object and the earth.
When earth angular velocity increase then gravitational acceleration increase?
Let's be very accurate when describing accelerations in this question. Consider a person at the equator. The gravitational force of attraction on him is constant whether or not the earth is rotating. This acceleration is called the acceleration due to gravity (ag) Now, since the earth is rotating about its axis, there has to be a centripetal force on the person. It is the gravitational force which provides the centripetal force. Thus, there is a centripetal acceleration on the person (ac) Finally, the rest of the gravitational force causes the person to accelerate towards earth. This is called the acceleration of free fall (af) This gives ag = ac + af ac is given by the equation: ac = w2r where w is the angular velocity and r is the radius of rotation If the angular velocity of the earth increases, centripetal acceleration will increase. af = ag - w2r Therefore, the acceleration of free fall will decrease.
Can any source of energy be pollution free?
In hydro power or solar power the energy source is pollution free but the process of manufacturing and building the plant is not of course.
What is the source of free energy for the leaf factory?
If by 'leaf factory' you mean the leaves of plants, then the source of free energy is the Sun, in the form of sunlight form the Sun.
Why is solar energy the best?
1. It is a reasonably constant source. 2. It is 'renewable'. 3. The source of the energy is free.
What source of energy is mostly pollution free?
Hydroelectric.
What is a advantage of solar power as a source of electricity?
It uses a free energy source that will not run out.
What is an advantage of solar power as a source of electricity?
It uses a free energy source that will not run out.
Why would somebody choose solar energy and not another energy source?
its renewable and free
What is the cheapest alternative energy source?
the cheapest alternative source of energy is biomass. because we can use it all and free and easy to find.
What forces cause acceleration?
A layman's attempt: Any unbalanced force applied over time to an object that is free to move will bring about acceleration.
Which of the following is an advantage of solar power as a source of electricity?
It uses a free energy source that will not run out.
Why is geothermal energy a good source of energy?
Geothermal energy is a free, natural resource. It is a renewable energy that will not run out and does not harm the environment.
