What is the formula for calculating acceleration?

Acceleration is a physical quantity that characterizes the change in velocity of an object over time. Acceleration indicates whether an object is speeding up, slowing down, or moving at a constant speed.

When do students in Vietnam learn the formula for calculating acceleration according to Physics curriculum?

In Section 4 of the Physics Education Program issued with Circular 32/2018/TT-BGDDT, the physics curriculum contributes to fulfilling the requirements regarding key qualities and general competencies for grade 10 students as follows:

*Changing motion

- Conduct experiments and make inferences based on the change in velocity in linear motion to derive the formula for calculating acceleration; state the significance and the unit of acceleration.

- Conduct experiments (or based on given data) to draw the velocity-time graph in linear motion.

- Use the velocity-time graph to calculate displacement and acceleration in some simple cases.

- Derive formulas for uniformly changing linear motion (without using integration).

- Apply the formulas of uniformly changing linear motion.

- Describe and explain the motion of an object moving with a constant velocity in one direction and a constant acceleration in a perpendicular direction.

- Discuss to design a plan or choose a method and implement it to measure free-fall acceleration using practical tools.

- Conduct a project or research topic to find the conditions to throw an object in the air from a certain height to achieve the greatest height or range.

Centripetal acceleration and centripetal force

- Apply the centripetal acceleration expressions a = rω², a = v²/r.

- Apply the centripetal force expressions F = mrω², F = mv²/r.

- Apply the concepts of amplitude, period, frequency, angular frequency, and phase deviation to describe simple harmonic motion.

- Use graphs, analyze and perform necessary calculations to determine: displacement, velocity, and acceleration in simple harmonic motion.

- Apply equations for displacement, velocity, and acceleration in simple harmonic motion.

- Apply the equation a = -ω²x for simple harmonic motion.

- Use graphs, analyze and perform necessary calculations to describe the transformation of kinetic energy and potential energy in simple harmonic motion.

Therefore, students will learn about acceleration in the grade 10 physics curriculum.

What is the content structure of the new physics curriculum in Vietnam?

In Section 5 of the Physics Education Program issued with Circular 32/2018/TT-BGDDT, it is clearly stated content structure of the new physics curriculum as follows:

What are the requirements for specific competencies for students when studying physics in Vietnam?

In Section 4 of the Physics Education Program issued with Circular 32/2018/TT-BGDDT, the subject of physics shapes and develops in students the competency in physics, expressed through the following specific indicators:

(1) Physics cognition

Understanding core general knowledge and skills about: physical system models; energy and waves; force and field; recognizing some sectors and professions related to physics; specifically expressed as:

- Identify and describe objects, concepts, phenomena, laws, and physical processes.

- Present physical phenomena and processes; characteristics and roles of physical phenomena and processes using representational forms: speaking, writing, measuring, calculating, drawing, schematics, and charts.

- Identify keywords, effectively use scientific terminology, logically connect information to create meaningful outlines when reading and presenting scientific texts.

- Compare, select, classify, and analyze physical phenomena and processes based on different criteria.

- Explain the relationships between objects, phenomena, and processes.

- Identify inaccuracies and correct understanding or explanations; offer critical judgments related to discussion topics.

- Recognize suitable career paths based on personal tendencies.

(2) Exploring the natural world from a physics perspective

Explore simple, familiar physical phenomena and processes in everyday life and the natural world through a sequence; use scientific evidence to test predictions, explain evidence, and draw conclusions; specifically expressed as:

- Propose physics-related issues: Identify and pose questions related to physics; analyze the context to propose questions by connecting existing knowledge and experiences and express the proposed questions in their own language.

- Make predictions and formulate hypotheses: Analyze issues to make predictions; build and articulate hypotheses that need exploration.

- Plan execution: Develop a logical framework for exploration; choose appropriate methods (observation, experimentation, investigation, interviews, literature research); draft an exploration execution plan.

- Execute the plan: Collect and store data from literature review, experimentation, investigation results; evaluate outcomes based on the analysis of data using simple statistical parameters; compare results with hypotheses; explain, conclude, and adjust if necessary.

- Write, present reports, and discuss: Use language, drawings, diagrams, and charts to articulate the exploration process and results; write reports on exploration outcomes; cooperate with partners positively and respect the viewpoints and evaluations provided by others to positively absorb, elucidate, counterargue, and convincingly defend the exploration results.

- Make decisions and propose opinions, solutions: Make decisions on addressing explored issues; propose suggestions for applying exploration and research results, or identify subsequent research problems.

(3) Applying acquired knowledge and skills

Apply acquired knowledge and skills in some simple cases, initially using mathematics as a language and tool to solve problems; specifically expressed as:

- Explain and prove a practical issue.

- Evaluate and refute the impact of a practical issue.

- Design models, draft plans, propose and implement some new methods or measures.

- Propose and implement solutions for nature conservation, adapting to climate change; possess reasonable behaviors and attitudes for sustainable development.

In the Physics Program, each component of both general competencies and specific competencies as mentioned above is incorporated into each topic, and each content area of instruction, in the form of required learning outcomes, with varying levels.
