In this first class of MECHANICAL ENERGY we will study the 3 main Mechanical Energies: 1) Kinetic Energy - associated with movement 2) Gravitational Potential Energy - associated with the difference in height of the object 3) Elastic Potential Energy - associated with the deformation of bodies In entrance exam exercises it is common for these 3 Energies to be associated and there is also CONSERVATION OF MECHANICAL ENERGY. The class of NEWTON'S LAWS can help in the good understanding of this class: • NEWTON'S LAWS - [PHYSICS FROM SCRATCH] 1st Law: PRINCIPLE OF INERTIA - a body at rest tends to remain at rest and a body in motion tends to remain in rectilinear and uniform motion 2nd Law: FUNDAMENTAL PRINCIPLE OF DYNAMICS - F = m . the 3rd Law: ACTION AND REACTION - same intensity, same direction, opposite senses I organized here for you some playlists to help you prepare for ENEM 2022 =) Complete KINEMATICS Playlist FROM SCRATCH: • KINEMATICS from SCRATCH This Playlist will cover the following topics: Initial Concepts of Kinematics, Average Speed, Average Scalar Acceleration, Uniform Motion (MU), Uniformly Varied Motion (MUV), Free Fall and Vertical Launch, Horizontal Launch, Oblique Launch Complete BASIC MATHEMATICS course: • Basic Mathematics (Complete Course) Playlist of Tips for MEDICINE: • MEDICINE - [ENEM 2020] ENEM Data Analysis Playlist: • ENEM ANALYSES Good studies! =)
