What is mechanical energy? What are trực tiếp bóng đá euro hôm nay formulas for calculating mechanical energy in trực tiếp bóng đá euro hôm nay 10th-grade Physics curriculum in Vietnam?

Mechanical energy isthe sum of trực tiếp bóng đá euro hôm nay energy possessed by a moving object, including both kinetic energy (energy due to movement) and potential energy (energy due to position). In other words, mechanical energy is trực tiếp bóng đá euro hôm nay ability of an object to perform work.

What is mechanical energy? What are trực tiếp bóng đá euro hôm nay formulas for calculating mechanical energy in trực tiếp bóng đá euro hôm nay 10th-grade Physics curriculum in Vietnam?

As stated earlier,mechanical energy is trực tiếp bóng đá euro hôm nay sum of trực tiếp bóng đá euro hôm nay energy possessed by a moving object, including both kinetic energy (energy due to movement) and potential energy (energy due to position).

Kinetic Energy (Wđ)

Is trực tiếp bóng đá euro hôm nay energy an object has due to its motion.

Formula: Wđ = 1/2 * m * v²

Where:

m: mass of trực tiếp bóng đá euro hôm nay object (kg)

v: velocity of trực tiếp bóng đá euro hôm nay object (m/s)

Potential Energy (Wt)

Is trực tiếp bóng đá euro hôm nay energy an object has due to its position relative to a reference point.

There are two main types of potential energy:

Gravitational potential energy:

Formula: Wt = m * g * h

Where:

m: mass of trực tiếp bóng đá euro hôm nay object (kg)

g: gravitational acceleration (m/s²)

h: height of trực tiếp bóng đá euro hôm nay object from trực tiếp bóng đá euro hôm nay ground (m)

Elastic potential energy:

Formula: Wt = 1/2 * k * x²

Where:

k: spring constant (N/m)

x: deformation of trực tiếp bóng đá euro hôm nay spring (m)

mechanical energy (W)

Is trực tiếp bóng đá euro hôm nay sum of kinetic energy and potential energy: W = Wđ + Wt

trực tiếp bóng đá euro hôm nay law of conservation of mechanical energy: In a closed system (a system with no external forces), trực tiếp bóng đá euro hôm nay mechanical energy of trực tiếp bóng đá euro hôm nay system is conserved. This means trực tiếp bóng đá euro hôm nay total kinetic energy and potential energy of trực tiếp bóng đá euro hôm nay system remains constant over time.

General formulas for mechanical energy in 10th Grade Physics:

When an object moves in a gravitational field:

W = Wđ + Wt = 1/2 * m * v² + m * g * h

When an object is only subject to elastic forces:

W = Wđ + Wt = 1/2 * m * v² + 1/2 * k * x²

*Illustrative Example

A falling ball: As trực tiếp bóng đá euro hôm nay ball falls, its gravitational potential energy decreases and transforms into kinetic energy. Upon hitting trực tiếp bóng đá euro hôm nay ground, all gravitational potential energy has been converted into kinetic energy.

An object attached to an oscillating spring: As trực tiếp bóng đá euro hôm nay object oscillates, kinetic energy and potential energy continuously convert into each other. At trực tiếp bóng đá euro hôm nay boundary position, kinetic energy is zero, potential energy is at maximum; at trực tiếp bóng đá euro hôm nay equilibrium position, kinetic energy is at maximum, potential energy is zero.

Is being able to specifythe concept of mechanical energyone of trực tiếp bóng đá euro hôm nay required outcomes in trực tiếp bóng đá euro hôm nay 10th Grade Physics curriculum inVietnam?

Under trực tiếp bóng đá euro hôm nay regulations in Section 5 of trực tiếp bóng đá euro hôm nay General Education Program in Physicsissued together withCircular 32/2018/TT-BGDDT, trực tiếp bóng đá euro hôm nay required outcomes in trực tiếp bóng đá euro hôm nay 10th Grade Physics curriculum are as follows:

Kinetic and Potential Energy

- From trực tiếp bóng đá euro hôm nay uniformly accelerated rectilinear motion equation with an initial velocity of zero, derive that trực tiếp bóng đá euro hôm nay kinetic energy of an object equals trực tiếp bóng đá euro hôm nay work done by trực tiếp bóng đá euro hôm nay force applied to trực tiếp bóng đá euro hôm nay object.

- State trực tiếp bóng đá euro hôm nay formula for calculating potential energy in an even gravitational field, applying it in simple cases.

- Analyze trực tiếp bóng đá euro hôm nay transformation of kinetic and potential energy of an object in some simple cases.

- State trực tiếp bóng đá euro hôm nay concept of mechanical energy; articulate trực tiếp bóng đá euro hôm nay law of conservation of mechanical energy and apply it in some simple cases.

Power and Efficiency

- From some practical situations, discuss trực tiếp bóng đá euro hôm nay physical meaning and definition of power.

- Apply trực tiếp bóng đá euro hôm nay relationship between power (or work execution rate) with trực tiếp bóng đá euro hôm nay product of force and velocity in some practical situations.

- From practical situations, discuss trực tiếp bóng đá euro hôm nay definition of efficiency and apply efficiency in some real cases.

Thus, according to trực tiếp bóng đá euro hôm nay current 10th-grade Physics curriculum, students must be able to specifythe concept of mechanical energy, articulate trực tiếp bóng đá euro hôm nay law of conservation of mechanical energy, and apply it in some simple cases.

What are trực tiếp bóng đá euro hôm nay requirements for10th-grade students to achieve trực tiếp bóng đá euro hôm nay "Good Student" titlefor trực tiếp bóng đá euro hôm nay whole school year in Vietnam?

Under point a, clause 1, Article 15 of trực tiếp bóng đá euro hôm nay regulations issued together withCircular 22/2021/TT-BGDDT:

Commendations

1.Principals shall award certificates of achievement for students

a) End-of-year commendation

-Award trực tiếp bóng đá euro hôm nay title “Học sinh Xuất sắc” (Excellent student) for students who have obtained Excellent training and learning results for trực tiếp bóng đá euro hôm nay entire school year and achieved DTBmcnof at least 9.0 in subjects that are assessed via both feedback and scores.

-Award trực tiếp bóng đá euro hôm nay title “Học sinh Giỏi” (Good student) for students who have obtained Excellent training and learning results for trực tiếp bóng đá euro hôm nay entire school year.

b) Commend students for having unexpected merits in training and learning in trực tiếp bóng đá euro hôm nay school year.

2.Students with special achievements shall be considered and requested for commendation by schools.

Additionally, according to clause 2, Article 9 of trực tiếp bóng đá euro hôm nay regulationsissued together withCircular 22/2021/TT-BGDDT:

Assessment of learning results of students

...

2.Learning results in each semester and school year

For subjects assessed via both feedback and scores, DTBmhkis used to assess learning results of a student in each semester while DTBmcnis used to assess learning results of a student in trực tiếp bóng đá euro hôm nay entire school year. Learning results of a student in each semester and in trực tiếp bóng đá euro hôm nay entire school year shall be assessed by one of 4 categories: Excellent, Good, Qualified, Unqualified.

a) Excellent:

-All subjects assessed with feedback are placed in Qualified category.

-All subjects assessed by both feedback and scores have minimum scores of 6.5 for DTBmhkand DTBmcnwith 6 subjects among which have minimum scores of 8.0 for DTBmhkand DTBmcn.

...

Thus, according to trực tiếp bóng đá euro hôm nay regulation, to achieve trực tiếp bóng đá euro hôm nay "Good Student" title for trực tiếp bóng đá euro hôm nay whole school year, all subjects assessed by both feedback and scores of 10th-gradestudentshave minimum scores of 6.5 for DTBmcn with 6 subjects among which have minimum scores of 8.0 for DTBmcn.
