中学物理竞赛大纲（Syllabus for physics competition in middle school） Syllabus for middle school physics competition (basic theory) Dynamics 1. Kinematics Frame of reference. The displacement, distance, velocity, acceleration of a particle motion. Relative velocity. Vectors and scalars. Synthesis and decomposition of vectors. Uniform and uniform rectilinear motion and its image. Synthesis of motion. Projectile motion. Circular motion. The translation of a rigid body and the rotation of a fixed axis. 2. Newtons laws of motion Several common forces in mechanics Newtons first, second, third law of motion. The concept of inertial frame of reference. Friction。 Elastic force. Hookes law. Law of gravitation. The gravity formula uniform ball shell on the shell and shell of ectoplasm (not required export). Keplers law. Motion of planets and satellites. 3, the balance of objects Concurrent force under the action of body balance. Moment. Balance of rigid body. Focus。 Types of object balance. 4, momentum Impulse. Momentum. Momentum theorem. Law of conservation of momentum. Recoil motion and rocket. 5 mechanical energy Work and power. Theorem of kinetic energy and kinetic energy. Gravitational potential energy. Gravitational potential energy. The formula of gravitational potential energy inside and outside a sphere (and not required to be derived) in a particle and a homogeneous spherical shell. The elastic potential energy of a spring.
