The formula for the energy of motion is: KE=0.5×m×v2 where KE is kinetic energy in joules, m is mass in kilograms and v is velocity in meters per second.Force and Work Newton's three laws of motion form the basis for classical physics. The first law defines force as that which ca...
The formula that relates power (P), energy (E), and time (T) is:P=ETWhere:- P is the power in watts (W),- E is the energy in joules (J),- T is the time in seconds (s). Hint: Remember that 1 watt is equal to 1 joule per second. --- Step 2: Rearrange the formula ...
E = energy (Joules, J) m = mass (kg) c = speed of light in vacuum ( ) Einstein's Mass-Energy Equivalence Formula Questions: 1) What is the rest energy of 1kg of water (or any other substance)? Answer:The rest energy, or the amount of energy that would be released if mass were...
Elastic potential energy = force x distance of displacement. W = Fs W = elastic potential energy, in Joules F= force, in Newtons s= displacement, m Because the force is = spring constant x displacement, then the Elastic potential energy = spring constant x displacement squared. F = 1/2 ...
The unit for strain energy is in joules (J). This unit is also equivalent to Newton-meter or Nm. Strain energy is the stored energy that depends on force (which is in terms of Newton) and change of length (which is in terms of meters). What is strain energy? Strain energy is store...
Energy is typically measured in Joules (J). Additionally, energy can come in many kinetic or potential forms, all of which can transform into all other types of energy through one or more steps.What is Energy? What is the meaning of energy? Energy is typically defined in science as the ...
