Is elastic energy useful in a bouncy ball or is it wasteful?
Missmoomin
It is usefull because how would the ball bonce without the being elastic energy in it???

What kind of energy does a wound clock spring have?
It can be described in several ways, but elastic potential energy is the most useful.
What is the useful and wasted energy in an electric heater a television an electric kettle headphones Thanks for your help?
The use ful energy from headphones would be sound , the wasteful would be battery power.
In a collision what is conserved?
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
When to use law of momentum to find velocity rather than law of conservation of energy?
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved. On the other hand, momentum is always conserved, whether a collision is elastic or inelastic. (In an elastic collision, energy is also conserved.) Thus, conservation of momentum is often more useful for calculations involving collisions.
How is gravitational potential energy useful?
it is the energy of position and most objects have gravitational potential energy, all they need is a height, and to NOT have a spring/elastic
Friction is inveitable but it has disadvantages why?
Friction is a force that must be overcome for no useful purpose. It takes energy to do this, and thus is wasteful.
Someone who is not-wasteful is.?
Useful. ECONOMICAL FRUGAL

How long will it take to make more energy when its all gone?
Energy can never be destroyed or 'ran out of', it can only be changed. E.g this is how energy is used in a torch: the chemical energy in the battery is transferred into light energy (which is useful energy in this instants), and into heat energy (which is wasteful in this instants). I may have said that heat was waisted but it can be used for other things, just not in a torch)! Hope that has answered your question.
What is wasteful energy?
by a bio gas Do you know that the US Government specifically the Dept of Defense is partnering with private companies to improve waste to energy projects? Read more about it by clicking the link.
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out is light energy. Heat energy is also produced but is not useful
Useful and non-useful energy transfers for coal?
Useful: Energy Light Sound Non-Useful: Electricity C02
Is it always easy to collect wasted energy and use it?
Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.
