Yan explains what happens if one person lets go in term of Newton’s first law of motion. So, there must be a centripetal force pulling inwards on anything moving in a circle. For the cup of ...

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 ...

Comman forces in mechanics. Static and kinetic friction, laws of friction. rolling friction, lubrication. Dynamics of uniform circular motion: Centripetal force, examples of circular motion ...

The Lagrange Points are celestial equilibrium zones, where the combined gravitational pull of two massive bodies equals the centripetal force that keeps a smaller object in rhythmic motion.

Newton’s Laws will help your students understand force, motion, and the transfer of energy. In this classroom presentation, engaging hands-on activities help demonstrate these important concepts your ...
