Back before Astronomy was well-understood, people used the "Apparent" motion of the Sun across the sky as the measure of the length of the day. Now that we know better, we measure the length of a day as one complete rotation of the Earth. This is known as a sidereal day (sigh-deer-ee-al) which is approximately 23 hours, 56 minutes, 4.09 seconds, corresponding to the time it takes for the Earth to complete one rotation with reference to the vernal equinox.

Temperature is the average energy of random motion of particles of matter :). Hope that helps
Heat is a measure of the amount of energy due to the motion of the particles in a gas, liquid, or solid. Temperature is a measure of the average amount of heat energy in a given body.

A tree can be used for a frame of reference for the motion of a snowboarder.
You can measure distance traveled, energy used or work done.

Motion detection devices can be used anywhere that you need an extra measure of security. Motion detectors can also be used for automated lighting control or to be more energy efficient.
No, it can only be used to measure temperature of an object.
The sunshine recorder is used to measure sunlight used in a day.
A goniometer is a device used to measure the range of motion in a joint. Medical professionals use them to determine the range of motion in human joints, while they can also be used to measure angles in inanimate objects.
A sensor is a device that is used to measure something and record it. It can measure heat, sound, light, frequency, or motion and respond to it.
Inertia is an objects resistance to change in motion. Frictional forces resist motion.
Torque is used to absorb the twisting motion of a load line. Torque is used to measure how much force the object being twisted can rotate on its axis.
