The video tutorial introduces the concept of kinetic energy, explaining it as the energy an object possesses due to its motion. The formula for kinetic energy is presented as KE = 1/2 mv², where m is mass and v is velocity. The tutorial includes a problem-solving example where an object with a mass of 100 kg traveling at 5 m/s is used to calculate kinetic energy, resulting in 1250 joules. The video concludes with a brief summary and closing remarks.
