Forces always occur in pairs. The two forces are of equal strength but in opposite directions.This still causes confusion because it sounds like these forces would always cancel each other out. This isn’t the case. Remember, the forces act on different objects. And just because the two ...
Contact force The push experienced when two objects are pressed together Weight The gravitational pull of the Earth on an object Friction A type of force that oppose motion. It exists between the the surfaces of two objects are in contact Tension The pull at both ends of a stretched string, ...
action/reaction forces always act in pairs Newton's 1st law "An object at rest will remain at rest, and an object in motion will remain in motion unless acted on by an unbalanced force" Newton's 2nd law "The acceleration of an object depends upon the mass of the object and the net ...

Also, action and reaction force pairs are present even when there is no motion (such as when a person sits on a chair). In addition, action and reaction forces in a pair don't act on the same object, and when a force is exerted, there is always a reaction force--a force never ...
Newton noticed that forces always come in pairs as a result of the interaction between two bodies and that the two forces were always equal in size and opposite in direction. In his third law Newton states: If body A exerts a force on body B, then body B exerts a force on body A th...
The goal of this activity is to show students that even the slightest forces will affect the motion of objects. An introductory activity, it encourages students to see the physics of motion as they relate to students' own bodies and environment. Students will divide into pairs, each of which...
