One joule represents (approximately): • The amount of electricity required to run a 1 W device for 1 s. • The energy required to accelerate a 1 kg mass at 1 m/s through a distance of 1 m. • The kinetic energy of a 2 kg mass travelling at 1 m/s, or a 1 kg mass travelling at 1.41 m/s. WebSummary. A kilojoule (or Calorie) is a unit of energy. In Australia, we use kilojoules (kJ) to measure how much energy people get from consuming a food or drink. The kilojoule content of foods depends on the amount of carbohydrates, fats and proteins present in the food, and the portion size. Foods that are high in fats, added sugars or alcohol ...
WebHow is a joule defined?(1 point) It is the force needed to make an object with a mass of 1 kilogram accelerate by 1 kilogram per second squared. It is the force needed to make an object with a mass of 1 kilogram travel 1 meter. It is the work done when a science Lesson 19: Collision Forces Quick Check 1. WebWork & Energy are also measured in Newton meters which are Joules. However, torque isn't a measure of energy. I am really confused as why it isn't measured in Joules. Minor note: Torque is usually given by r F sin θ, not just r F, unless the angle is always 90 degrees of course because sin 90 = 1.
