A. the mass of the object B. the velocity of the object C. the square of the velocity of the object D. the product of the mass and the velocity of the object 相关知识点: 试题来源: 解析 C。动能“kinetic energy”与物体速度的平方成正比。动能公式为 E=1/2mv²。选项 A 仅质量不行...
Definition/Summary Kinetic energy (KE) is energy associated with movement as a whole (linear or rotational or both). Kinetic energy of a body...
The energy of an object can be in the form of kinetic energy, potential energy, thermal energy, internal energy, chemical energy, electrical energy, nuclear energy, and so on.Answer and Explanation: Kinetic Energy: The kinetic energy (KE) is in the form of energy on an object due to its...
A car of mass 500 kg is moving at a speed of 20 m/s. What is its kinetic energy? A. 100000 J B. 10000 J C. 20000 J D. 50000 J 相关知识点: 试题来源: 解析 A。动能的计算公式为 Ek = 1/2mv²,代入数据可得 Ek = 1/2×500×20² = 100000 J。选项 B 计算错误,选项 C...
Kinetic energy is energy that an object possesses when it is in motion, or the amount of work it would take for an object to...
What Is Kinetic Energy: The word "kinetic" means movement, as you might have heard in the term kinesthetic learner, or one who learns by doing hands on activities. So, kinetic energy is energy due to movement. Anything moving, from the electrons flowing through the wires to your computer,...
简谐运动（Simple harmonic motion）（SHM）（直译简单和谐运动）是最基本也最简单的机械振动。当某物体进行简谐运动时，物体所受的力跟位移成正比，并且总是指向平衡位置。它是一种由自身系统性质决定的周期性运动。（如单摆运动和弹簧振子运动）实际上简谐振动就是正弦振动。故此在无线电学中简谐信号实际上...
Anything that creates vibrational, rotational or translational energy is kinetic energy. Most forms of energy in the world are considered kinetic energy, because the energy is created by one or more objects acting against an environment or another object. Production of this energy type is simple. ...
NZ has energy-component 1 mass-diamond =(0.17 MeV) and momentum-component -1 mass-diamond = -(0.17 MeV). The velocities are gotten from the slopes of the 4-momenta. The electron's final kinetic energy is the final energy-component minus the mass-energy = ((5-3)*0.17 MeV)...
Mechanical energy is the energy possessed by an object by virtue of its mechanics. The mechanical energy is of two types Kinetic Energy Potential Energy Potential energy can be of further many types. Answer and Explanation:1 Kinetic Energy ...
