1. according to the video, energy is the capacity to do
motion
work
2. according to the video, energy is the energy of particle motion.
heat
potential
3. according to the video, energy is the motion of electrons.
mechanical
electrical

Explanation :

(1). Work is said to be done when a force is applied in order to create some displacement and energy is defined as the capacity to do work. Its SI unit is Joule (J).

(2). Heat energy is defined as the energy due to the motion of particles. the heat energy depends on the temperature and number of atoms. Higher the temperature, more will be thermal or heat energy.

(3). Electrical energy is defined as the energy possessed due to the motion of electric charges. The electric charges in a circuit are negatively charged electrons.  

So, the correct words in given blanks are :

(1) Work

(2) Heat energy

(3) Electrical energy
