The article presents research results and develops experiments in teaching energy and momentum - physics grade 10 with the support of Coach 7 software, including: Experiment to verify the law of conservation of mechanical energy of a simple pendulum, experiment to verify the law of conservation of momentum in elastic collisions (collision in different directions, collision in the same direction), experiment to verify the law of conservation of momentum in soft collisions. With the advantage of simple operations, diverse processing data, intuitive and accurate results, and low cost, can be deployed conveniently as student experiments, the built experiments are an effective alternative for high schools when teaching the energy and momentum - physics grade 10 to achieve the requirements of the program, contributing to the development of physics competence of students.
