A force is a push or pull that acts upon an object as a result of that objects interactions with its surroundings. In this Lesson, The Physics Classroom differentiates between the various types of forces that an object could encounter. Some extra attention is given to the topic of friction and weight.

Two forces acting against each other are opposing (the two different pulls in a tug of war, for example). If one of these forces is stronger than the other one, it will always win. If the opposing forces are pushing or pulling something with equal strength, the object will not move because the two forces are balancing each other.
A force is a push or pull on an object. A net force is the sum of all of the forces acting on an object. When there is a net force on an object, the object will change speed in the direction of the net force. The object’s acceleration tells us how much it speeds up or slows down.
Sep 26, 2017 · The subscript AB indicates that A exerts a force on B, and BA indicates that B exerts a force on A. The minus sign indicates that the forces are in opposite directions.
Newton's Third Law. Identifying Interaction Force Pairs. A force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions!
When forces in a particular dimension cancel each other out, they're balanced and result in zero net force. When forces in a particular dimension do not cancel each other out, they're unbalanced and result a nonzero net force. Explore balanced and unbalanced forces through five different scenarios involving a rock and various forces acting on it.
Feb 22, 2011 · The two main forces that oppose your motion are aerodynamic drag (air resistance) and rolling resistance of the tyres against the road. Your forward force comes from pushing and pulling on the pedals to make the back tyre push backwards against the road.
