When a body or object moves in a circle, it is said to be in a circular motion. That is we can say that motion in a circle is a circular motion. When a body or object moves along a circular path, then ...

Motion is movement of an object from one place to another or we can say it is the process of moving, changing place or position. Motion requires force to cause that change. The time you take to travel ...

Why study physics, you ask? Scroll down, friend. This video of a guy rolling through a 360-degree vertical loop at a skatepark—cool as ice, with no helmet—is answer enough. Clearly, his understanding ...

Polar orbits take the satellites over the Earth's poles. The satellites travel very close to the Earth (as low as 200 km above sea level), so they must travel at very high speeds (nearly 8,000 m/s).

Gravitational attraction provides the centripetal force needed to keep a planet in orbit around the Sun, and a satellite in orbit around a planet. For example, gravitational attraction between the ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

Abstract: Accurately and continuously tracking object vehicles and obtaining their motion information are crucial for safe decision-making and planning in autonomous vehicles. However, the existing ...
