When you swing a ball on a rope in a circle above your head, what keeps it moving in that circular path? This applies to any object moving in a circle, not just a ball on a rope - the force and ...

Newton's first law can also be used to explain the movement of objects travelling with non-uniform motion. This includes situations when the speed changes, the direction changes, or both change. For ...

Learn the key differences between centripetal and centrifugal forces, their real-world applications in physics, and how they shape our understanding of circular motion. When you purchase through links ...

Abstract: This paper proposes that a mass point moving horizontally in a circular motion on the Earth’s surface can generate a radial centrifugal force in the center of the Earth, thus realizing a non ...

Listen to the full series on BBC Sounds. Newton's first law can also be used to explain the movement of objects travelling with non-uniform motion. This includes situations when the speed changes, the ...

Abstract: This paper presents a power assist robot system developed for manipulating objects in horizontal direction in cooperation with a human. Weight perception was included in robot dynamics and ...
