The Application of Mobile Intelligent Terminal in High School Physics Learning

3 THE ROLE POSITIONING OF MOBILE 
INTELLIGENT TERMINAL IN HIGH 
SCHOOL PHYSICS TEACHING 
3.1 Pre-class Preview Stage 
The curriculum content of high school physics is very 
complex, the learning difficulty is relatively large, the 
chapters are also very abstract, and the high school 
students have a long study time, and the study schedule 
is relatively tight. Therefore, when learning high school 
physics, it must also grasp the pre-class preview stage, 
and do a good job of pre-class preparation. Physics 
teachers can use mobile smart terminals one to two days 
in advance to publish learning tasks and books on 
educational platforms such as WeChat or Dingding. The 
study guide for the lesson allows students to preview the 
lesson according to the study guide and consult the 
relevant learning materials, so that students can think 
about the learning content of this lesson in advance. Then 
teachers in class ask questions based on their own 
thinking, so that students can better clarify the key points 
and difficulties in this section of the course, improve 
students’ attention, and improve the efficiency of physics 
courses. At the same time, it can also effectively cultivate 
students’ independence. 
3.2 Organize the Teaching Stage in the Class 
In-class organization and teaching stage is an 
important content in high school physics curriculum, and 
it is also the main problem that teachers need to spend a 
lot of time and energy to solve. In order to effectively 
improve the learning efficiency of high school physics 
classrooms, concentrate the attention of high school 
students, and improve the goals of high school physics 
teaching, physics teachers can adopt modern teaching 
methods, build efficient physics classrooms, and use 
multimedia equipment to play corresponding learning 
videos or make micro lessons, make animations, and 
focus the attention of high school students. Secondly, the 
use of mobile smart terminals can effectively improve

students’ learning efficiency. Compared with traditional 
multimedia devices, mobile smart terminals can 
effectively meet the individual needs of students, allow 
students to actively participate in school classrooms, and 
better achieve the goal of high school physics teaching. 
For example, when explaining the law of universal 
gravitation, students can collect learning tasks from 
teachers through mobile smart terminals such as smart 
tablets in their hands, and then write the derivation 
process of the formula on the smart tablet. At the same 
time, teachers can randomly project students’ tablet 
content, share learning results with students, and allow 
students to answer actively, understand the process of 
students’ thinking. Teachers can summarize and explain 
the correct derivation process, so as to better achieve high 
school the goal of physics teaching [3]. 
Prove: There are two isolated objects whose masses 
are M and m respectively, the distance between them is r, 
and the period of m making uniform circular motion 
around M is T. 
The universal gravitation of M on M F provides 
centripetal force as follows.

According to Newton’s third law, the gravitational 
attraction of M on M is also F, and has the same property. 
So the gravitational attraction of m with respect to 
M is F∝
