A motion detector is an alarm peripheral that requires an alarm control panel to receive signals, which can trigger a siren and begin communicating with the central station.
Electrical? Anything that produces light, heat, or motion when powered
Do yo mean Parachute a device used to slow the motion of an object through an atmosphere by creating drag,
Gravity and Calculus. If you're more interested in a scale model of the solar system, a device called an "Orrery" will do it for you. An Orrery is a clockwork model of a solar system.
It can't. That's the simplest way to explain why no successful perpetual motion machine has ever been built. --------------------------------------------------------------- Another contributor persisted: well it's just a matter of time and life!
Linear Motion, reciprocating motion, rotary motion, and oscillating motion
A Passive InfraRed Sensor (PIR)
A wanderer monitoring sensor is a device used to track the movement and location of individuals within a specific area. It typically utilizes technologies such as GPS, RFID, or motion sensors to provide real-time monitoring and alerts for security or safety purposes.
The scotch yoke is a mechanism that reciprocates motion and converts the horizontal motion of a bar that is constantly sliding into a rotational motion. This device is commonly used to control valve actuators that can be found in gas pipelines.
Yes it is, a PIR stands for Passive InfraRed, which detects heat signatures. For a higher level of security, I would recommend dual band motion detectors with PIR and Microwave Detection capability.

The Cam
The Angelcare Deluxe Movement Sensor provides the largest range for in-home monitoring. This comes with a motion sensor that will alert the mobile units as to when there is motion in the room it is monitoring.

It's called a "Motion Detector"!
Solenoid --- A solenoid produces linear motion. It's an electric motor that produces rotary motion.
Force and motion might be associated with a safety device.
