The so-called "astronomical unit" is often used for this. One AU (astronomical unit) is the average distance from Sun to Earth; it is about 150 million kilometers.
The distance between planets are measured in millions of kilometers while the distance between solar systems are measured in light years while the galxies and the universe are measured in AU (astronautical units)
Thermal energy is present when there is a difference in temperature between two objects or systems. This energy is a form of kinetic energy associated with the random motion of particles in those objects or systems. Its presence can be detected through changes in temperature or by measuring the amount of heat transfer between objects.
Mechanics deals with the motion of objects and the forces acting on them, while thermodynamics focuses on the relationships between heat, work, and energy transfer. Mechanics is concerned with the behavior of macroscopic objects, while thermodynamics looks at the macroscopic properties of systems in equilibrium.
Magnetostrictive materials are used in sensors and transducers to accurately measure distances, positions, and movements. They are also used in devices such as actuators, motors, and sonar systems due to their ability to convert magnetic energy into mechanical motion.

Scientists measure distances to stars to determine their exact positions in the sky and their relationships with other astronomical objects. By observing how stars interact with each other, scientists can understand the dynamics of star systems, galaxies, and the Universe as a whole, helping to unravel the mysteries of celestial phenomena.
Pulleys in mechanical systems provide advantages such as increased mechanical advantage, reduced effort required to lift heavy objects, and the ability to change the direction of force. They also allow for the transmission of power over long distances and can be used to create complex systems for lifting and moving objects efficiently.
Energy can be transferred between objects or systems through various mechanisms like conduction, convection, and radiation. In conduction, energy is transferred through direct contact between objects, while convection involves the transfer of energy through the movement of fluids. Radiation is the transfer of energy through electromagnetic waves.

There are an enormous number of uses of trigonometry and trigonometric functions. For instance, the technique of triangulation is used in astronomy to measure the distance to nearby stars, in geography to measure distances between landmarks, and in satellite navigation systems. Wikipedia has a page on the uses of trigonometry. Click on 'related links' below to go to that page.
An odometer for measuring long walkable distance. Long distances on the earth are probably best measured by geographical positioning systems (GPS).
Radio waves are used in various practical applications such as broadcasting information over long distances (radio and television transmission), communication between electronic devices (Wi-Fi, Bluetooth), radar systems for navigation and tracking objects, and medical imaging (MRI).
To perform a time to collision calculation, you need to measure the distance between two objects and their relative speed. Then, divide the distance by the relative speed to determine the time it will take for the objects to collide. This calculation helps predict potential collisions and is commonly used in traffic safety systems.
A radar device uses reflected electromagnetic waves to measure the distance and direction of faraway objects. Radar systems emit radio waves and analyze the signals that bounce back to determine the location and movement of objects like aircraft, ships, or weather formations.
