at 4:42, qE(d1-d2) as E*d1=V1 , E*d2=V2 ,so eventually q(V1-V2). I was stuck here and found out the connection, like qE is force similar to mg is a force. Thanks sir.

At 3:30 the object "gains energy". Actually no energy is gained. It is converted from potential energy to kinetic energy. Maybe you meant to say it "gains kinetic energy"?

[@aruntejareddy7198]

@David same doubt it loses potential energy
