Can leaving lights on only in the rooms you are moving between save energy?

Of course not. When the light is on, it uses energy; when it is off, it doesn't, 'tis as simple as that. I have heard certain rumors that turning it on will use (for example) the equivalent of two hours of just being normally on. Since turning the light on takes but a few seconds, a simple calculation shows that this would produce enough current to trip any standard fuse or circuit-breaker. What's more, I personally turned a one of those lights (40 Watts) on and off 40 times in a row, and checked the energy usage. According to the above mentioned rumor, this would have to use about 2 kWh; the meter didn't advance a single kWh. Unfortunately, I don't have the equipment to do finer measurements, but it just doesn't make sense.

What is the kinetic energy called when it is moving?
Kinetic energy is when it's moving. Potential energy is when the object is motionless.
Does the glowing of a neon light caused by an electron emitting energy as it is moving from lower to higher energy levels?
No, other way around. The energy difference between the higher level and the lower, appears as photon energy.
Is a hammer held above a nail kinetic energy?
No, the word 'Kinetic' literally means moving. So Kinetic energy literally means moving energy. If your hammer is above a nail then it is not moving... and so it is not kinetic energy.
What is kinetic energy-?
Kinetic energy is energy that is posessed by a moving mass.
Does an electron lose or gain energy while moving up and down an energy level?
depends. Moving from an inner level to an outer level, the e- absorbs energy. Moving from an outer level to an inner level, the e- loses energy.
Which action doesnot save the energy in your home?
Leaving lights on in only thr rooms you are moving between.
Why is energy running out?
Because so many people are moving to Englsnd and leaving lights or anything to do with energy on.
What type of energy does a rollercoaster use?
potential when it starts ,then kinetic when it starts to move ,then lights if the roller coaster has lights ,then heat because of the friction between the tracks of the roller coaster and the actual car and it also has heat because every thing has heat energy no matter what
Are lights in the sky planes or what?
If the lights are moving, it is most likely they are planes. If the lights are not moving, it is most likely they are stars.
What is the clue that energy is moving between two objects?
[object Object]
What is heat energy moving between two touching objects called?
conduction
Heat energy moving between two touching objects is called?
conduction
What is the difference between dynamic strength and static strength?
well the static energy is the strength that resides in your body when you're not moving but dynamic energy is that the one occurs when you moving like swimming
What is the difference between potential and active energy?
Potential energy is energy that has the potential to be active. For example, when you pick up a pen, that is gravitational potenial energy, becasue it has the potetial to be dropped, in grvaity. Active energy would be when the pen is droppped and it is moving, it is active. It has a source of energy. Active energy is energy that is moving and working.
What is the relationship between kinetic energy of molecules and their physical state?
The relationship between kinetic energy of molecules and their physical state is simple. The higher the kinetic energy the faster the molecules move. The fastest moving molecules are gaseous and the slowest moving molecules are solids.
What is the difference between stored energy and energy in motion?
Stored energy is potential energy and energy in motion is kinetic energy. A pendulum has potential energy at the end of it's stroke and kinetic energy when it's moving.
What is the energy of a moving object called?
The energy of a moving object is called the Vector energy. It is also called Kinetic energy but there is a distinction between Potential energy a real energy and vector energy a vector. it is not clear in physics whether Kinetic energy is a vector or real energy. For example 1/2 mv^2 is called kinetic energy but it is not vector energy.
