such as gravity or magic attraction/repulsion. A contact force has o ponents. The part of the force that lies within the plane of contact is friction which must be overe for the o objects to slide relative to one another along that plane. The part of the force that is perp...

This is something my high school physics teacher could never tell me. I posed the hypothetical "if i tie a rope to you and pull, it's the rope pulling and moving you. But what is pulling when it comes to gravity?" Gravity is more of an effect rather than a force. Massive objects ...

Is centripetal force contact or noncontact? Is centripetal force caused by friction? In the centripetal force equation, what is the mass equal to? What is the difference between centripetal and centrifugal force? What direction is centripetal force? Does gravity affect centripetal force? Does centripe...
gravity. leaves falling from a tree is an example of non-contact force. electromagnetism is another example of a non-contact force. there are various examples from electrostatics showing the attraction of small materials towards an object. when an electric current is passed through iron, converting...
