Burglars and others with less than honorable intent do not like to be suddenly illuminated since his activities typically depend on stealth. A sudden change in the lighting causes people to look, and the burglar will typically want to avoid having anyone notice the guy breaking into a house or business.
The proportional counter is operating in linear mode, so the energy pulse measured by the detector is proportional to the energy of the radioactive particle. Thus, the average current flow in the detector is a function of both the activity (curies) and the energy (kEv) of the source. This detector is better at measuring the dose rate of the source. The Geiger-Muller detector, on the other hand, operates in avalanche mode, so the energy pulse measured by the detector is not proportional to the energy of the radioactive particle. Thus, the average current flow in the detector is a function of only the activity (curies) of the source. This detector is better at measuring the activity of the source, and can be more sensitive to lower energy particles, at the loss of discrimination of what those particles are.
Energy due to motion is called kinetic energy.
Because the definition of "kinetic" energy is the Energy of [atomic] motion.
Motion. The motion can be energized by virtually any source of energy.
It's kinetic energy.
The main difference between the solar cell and detector is that the cell stores the energy, while the detector directs the energy towards the cell.
Energy that is motion or stands for motion is Kinetic Energy.
Motion.
An infrared detector
The main disadvantages of a motion sensor are that: It might not cover a full room. Things may trigger the motion detector that you don't want to. An outside detector mounted too close to a light that stays on at night, will be triggered continuously by bugs. The set shutoff time of the motion sensor may be too short (maybe only 30 seconds). For outside lights with a motion detector, if you want more "on time", it's best to buy a model with an adjustable shutoff time. The reliability of a motion sensor may also be affected by rapid environmental changes and direct sunlight. Also, things like a fireplace, and direct wind from an air conditioner or heater. This is because a PIR sensor actually detects changes in infrared energy - specifically, the "heat energy" emitted by normal human skin temperature.
A ball going down a hill is energy in motion. You walking is also energy in motion. A car moving is another example of energy in motion.
The energy of motion is called kinetic energy.
The energy of motion is called kinetic energy.
A PIR Sensor can be purchased at any specialty electronics store. It is a sensor primarily used for sensing changes in infrared energy. It is a highly specialized motion detector.
Kinetic energy is energy of motion. The kinetic energy of an object is the energy it posses because of its motion.
