B Physics 101 refresher question -- Confused about the definition of a Joule we all know the equation for KE 1/2mv^2 you do this simple math and you get an number that is in KE units , Joules. so, why is the KE unit equation, 1 Joule = Kg x (m^2/s^2) ?? 1Kg traveling...
Work = 200 joules Ajoule, a term used in physics, is equal to the kinetic energy of 1 kilogram moving at 1 meter per second.

The International System of Measurement units (SI units) used for torque is newton-meters or N*m. Even though newton-meters are equal toJoules, since torque isn't work or energy so all measurements should be expressed in newton-meters. Torque is represented by the Greek letter tau:τin cal...
Step 1:Energy =work done. W = f.dx Step 2:Insert the value of the force and displacement, in Newtons, and distance in meters = 30 � 5 Step 3:Write down the final answer in joules. Step 4:W=150j Related Terms: Energy | Work...
