Although a joule is 1 newton-meter, energy is not normally referred to using the latter unit, to avoid confusion with the unit of measure for torque, or moment of force, which has to do with rotational motion. Force, Work, Energy and Power There is often some confusion between these te...

Joule.The standard unit of heat in theInternational System of Units. One joule is equal to 1 newton multiplied by 1 meter (J = N ⋅ m). A joule can also be expressed by the formula J = kg⋅m2⋅s-2, wherekgis kilograms andsis seconds. Calorie.The amount of thermal energy trans...
The joule (symbol: J) is the basicSI unitofenergy. A joule is equal to thekinetic energyof a kilogrammassmovingat the speedof one meter per second (one joule is a kg⋅m2⋅s−2). Alternatively, it is the amount of work done on an object when a force of onenewtonacts in the ...
A joule is defined as the amount of energy transferred to an object when a force of one newton acts on the object in the direction of its motion through a distance of one meter (1 newton meter or Nm). It can also be defined as energy dissipated as heat when an electric current of ...
A joule is equal to one what times one meter? Unlike kinetic energy, potential energy is What metric unit do we use to denote velocity? If the kinetic energy of a particle is doubled, by what factor has its speed increased? Can the kinetic energy of an object be negative?

结果1 题目Which of the following is not a unit of force? A. Newton B. Joule C. Dyne D. Pound 相关知识点: 试题来源: 解析 B。牛顿(Newton)、达因(Dyne)、磅(Pound)都是力的单位,而焦耳(Joule)是能量单位。本题涉及力的单位的物理知识,阅读技巧是区分不同物理量的单位。
1 Joule = 1 Newton-meter. Depending on the problems often Nm are not converted to Joules until the end of the problem so that the canceling of units is more obvious. 1 Examples: i. Starting from rest a 2.5 kg block slides 3.0 m down a 50° incline. The coefficient of kinetic ...
