The most difficult topic for the Italian physics teachers to teach online was Accelerated motion and Newton's second law, especially in relation with: - Description of movement and straight steady movement and repetition; -Steady accelerated movement; - Path at steadily accelerated motion. They, also, found difficulties in teachingDensity, pressure and buoyancyin relation to: - Density and specific gravity; - Fluid pressure; - Pressure due to the weight of the stationary fluid; - Atmospheric phenomena and weather. Target group: studeNts For students, the most difficult Physics subjects in learning online were: ● Forces ● Accelerated motion and Newton’s second law ● Density, pressure and buoyancy In relation toForces they found it more difficult to understand the concept of Description of forces, Spring balance and Drawing forces. Accelerated motion and Newton's second lawhas been difficult for students about: Relationship between mass and weight and Steady accelerated movement. RegardingDensity, pressure and buoyancythey found more difficulties in relation to: - Density and specific gravity - Fluid pressure - Pressure due to the weight of the stationary fluid - Buoyancy 36
