Hey YouTube guys!!! In this video I will start the study of Kinetic Energy. Explaining the theory step by step in a didactic and objective way o/ Do you want to learn everything about Kinetic Energy? Subscribe! Big hug and good studies! LINK TO MY PHYSICS PLATFORM: ➡️ https://linktr.ee/Prof.Davi Example 01 A body with a mass of 500 g has a constant speed of intensity 36 km/h. Calculate its kinetic energy. Example 02 Despite the tragedies that occurred with the North American space shuttles Challenger and Columbia, which ended the lives of 14 astronauts, these reusable vehicles have been fundamental in the exploration of the cosmos. Assume that a space shuttle with a mass equal to 100 t is in the process of re-entering the atmosphere, presenting a speed of intensity 10,800 km/h in relation to the Earth's surface. What is the kinetic energy of this vehicle? Example 03 The equation for the speed of a 20 kg object is given by V = 3 + 0.2t. We can state that the kinetic energy of this object, at time t = 10s, is: Example 04 A particle A has mass m and moves at speed v. Another particle B has mass equal to 2 m and moves at speed V/2...
