A force is needed to: a change the state of motion or state of rest of the body b keep the body in motion c keep the body stationary d keep the velocity of body constant.
The meaning of FORCE is strength or energy exerted or brought to bear : cause of motion or change : active power. How to use force in a sentence. Synonym Discussion of Force.
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
总保持匀速直线运动状态或静止状态,直到有作用在它上面的外力迫使它改变这种状态为止 Any object in not any external force time, always maintains the uniform rectilinear translation condition or the static condition, until has the function to force it in it above external force to change this condition ...
aThis is the first time that I have come here 这第一次是我来这里[translate] aNewton's First Law says that an object will continue in its state of motion unless compelled to change by a force impressed upon it 牛頓的第一法律認為對象在行動它的狀態將繼續,除非由力量強迫改變被銘記在它[trans...
In other words, force is necessary to change the state of motion of an object. How does force affect the motion of an object? The acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass. This can b...
The motion of a rigid body in a plane is represented by a combination of a translation of the center of mass and a rotation. As illustrated in Fig. 1.1, the center of mass is labeled as S. The position of point S and the orientation of the object can be described by two vectors, ...
Forces change the quiescent or motile state of a body to which they are applied. According to Newton's second law, under the application of a force F = mdv/dt, a body of mass m moves with an acceleration dv/dt. In the last 20 years, especially in the field of robotics, intensive ...
Coriolis showed that, if the ordinary Newtonian laws of motion of bodies are to be used in a rotating frame of reference, an inertial force—acting to the right of the direction of body motion for counterclockwise rotation of the reference frame or to the left for clockwise rotation—must be...
PAMs deliver a safe and compatible interaction with the human environment only by controlling the volume flow rate of operating air into the muscle. Simple PAMs can be fabricated from inexpensive materials, which reduce the overall manufacturing cost. PAMs provide the linear contractile motion with a...
