2024年10月1日 · Newton’s second law of motion is one of the three fundamental laws formulated by Sir Isaac Newton. It describes how the motion of an object changes when a force is applied to it. The second law provides the quantitative relationship between force, mass, and acceleration, laying the groundwork for analyzing everything from the motion of ...

牛顿第二定律说明了力是物体运动状态发生变化的原因，与牛顿一、三定律一起作为 经典力学 的基石。 物体的运动变化与受力成正比，并且方向指向力的方向。 [14] 在实际情况中，质量、力和速度都有可能随时间变化。 一般地，牛顿第二运动定律的数学表达式是. 作用在物体上的力符合矢量叠加的法则，因此物体运动状态改变的方向是合力的方向。 对于质点，如果所受合力为零，那么质点的动量就不会改变，此时我们称之为质点处于机械平衡状态。 最初，牛顿第二定律是用 …

2022年2月1日 · The fundamental characteristic of Newton’s second law is the equation connecting the force, mass, and acceleration. English physicist and mathematician Isaac Newton postulated that acceleration is directly proportional to the …

Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, unless it is acted upon by a force.

Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

Newton’s second law states that the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object. The acceleration of the body is directly proportional to the net force acting on the body and inversely proportional to the mass of the body.

Newton’s second law of motion, also known as the law of acceleration, states that the magnitude of the force acting on an object is equal to the product of the mass of that particular object and the acceleration with which it moves.

2024年8月4日 · Newton’s Second Law of Motion is a fundamental principle that explains how the velocity of an object changes when it is subjected to an external force. This law is important in understanding the relationship between an object’s mass, the …

2025年2月13日 · Newton’s laws of motion - Force, Mass, Acceleration: Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

2021年5月13日 · Sir Isaac Newton first presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" in 1686. His second law defines a force to be equal to the differential change in momentum per unit time as described by the calculus of mathematics, which Newton also developed.
