In this second class of DYNAMICS we will begin the subject by talking about the TYPES OF FORCE - WEIGHT, NORMAL AND TRACTION FORCE. In this class we will see: Weight force, Gravitational force (gravity) Normal force, Traction In the previous class we studied Newton's Laws, which will be very important for ENEM and other entrance exams. Newton's 3 laws: • 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 . 3rd Law: ACTION AND REACTION - same intensity, same direction, opposite directions In DYNAMICS, famous quantities such as newtons, acceleration, speed, among others, will be studied.
