... there is no centrifugal force acting on the ladybug. We do see centripetal force acting on the can. In the rotating frame of reference of the whirling can, both centripetal force and centrifugal force act on the ladybug. However, centrifugal force is an effect of rotation. It is not part of an inter ...

... The weight W of an object is the (attractive) gravitational force acting on it: W = mg. On the Earth’s surface the gravitational field strength is g = 9.8 N/kg, so 1 kg weighs approximately 9.8 N. Energy (E) joule (J) Scalar 1 joule is the energy change when a force of 1 newton acts through 1 metre. ...

Motion of a charged particle under the action of a magnetic field
... The force is always perpendicular to velocity, so it cannot change the magnitude of the velocity, only its direction. The work done by the magnetic force is zero! Motion of a charged particle under the action of a magnetic field alone is always motion with constant speed. ...
