aIf the forces acting on a particle are not balanced, the particle will experience an acceleration proportional to the resultant force and in the direction of the resultant force. 如果行动在微粒的力量不是平衡的,微粒将体验加速度比例与合力和朝合力的方向。 [translate] ...
[translate] aa force of the same magnitude but acting in the opposite direction acts on the howitzer during the firing, a consequence of the third law of motion 同一巨大,但行动的力量在相反方向在短程高射炮在生火期间,第三运动定律的后果行动 [translate] ...
The acting force and counter-acting force acceleration magnetomotive device has the advantages that magnetomotive force can be generated under the repulsion and attraction effects of S (south)-pole surfaces inside columnar opening magnets with circular holes and S-poles and N (north)-poles of ...
We describe a rigidly mounted optical cavity that is insensitive to inertial forces acting in any direction and to the compressive force used to constrain it. The design is based on a cubic geometry with four supports placed symmetrically about the optical axis in a tetrahedral configuration. To ...

Identify the direction of the first force: The first 650-N force is acting in a northwesterly direction. This means it has components both to the north and to the west. Determine the desired resultant direction: The resultant force should point directly westw...
The frictional force acting on a component always acts in a direction opposite to the motion of the component. Two basic facts about friction have been experimentally established: 1. the frictional force is a function of the normal load on the contact, F = μP, where μ is the Coefficient...
