Preparation course for physics olympiads, grade 7 - free course from Foxford, training 30 lessons, date: December 4, 2023.
Miscellaneous / / December 08, 2023
During the classes, material that is not included in the school physics curriculum is presented in clear language: kinematics, statics, hydrostatics and other topics.
Who will benefit from the course?
A course for 7th grade students who are studying the subject from scratch and want to gain in-depth knowledge to participate in physics Olympiads.
What knowledge does the course provide?
The course presents in clear language material that is not included in the school physics curriculum: kinematics, statics, hydrostatics and other topics.
What skills does the course provide?
The course will teach you how to solve Olympiad problems on 7th grade topics, as well as understand non-standard approaches to solving them.
We manually check samples and homework
We do not leave the written part assignments for self-testing - this is done by OGE experts.
We check “for real”, like in an exam, and as a result you receive detailed feedback. All this is for the sake of speed of preparation and your results.
A personal curator will answer questions within two hours, 24/7
The curators understand the program and the subject, so they can easily answer your questions about the course and homework - at any time
They know well how difficult it can be to prepare and understand your worries.
The most important task of a tutor is to help you cope with stress and fear before exams
The lesson lasts 2 academic hours.
Measurements in physics
The section is devoted to the study of units of physical quantities, as well as the international system of units.
- Measurements in physics
- International System of Units (SI)
Kinematics
The section covers the basic concepts of kinematics and also examines how problems change with the advent of acceleration.
- Uniform linear movement
- Average speed
- Relativity of mechanical motion. Law of addition of speeds
- Acceleration
Mass and density. Powers
The section teaches special approaches for finding the masses and densities of various substances, and mixtures and alloys are also considered. In addition, the basic concepts of forces and their qualitative application in Olympiad problems in physics are touched upon.
- Weight. Density
- Calculation of densities of mixtures and alloys
- Newton's laws
- Elastic force
- Friction force
- Movable and fixed blocks
Preparing for the Maxwell Olympics
The section examines both the theoretical round of the Maxwell Olympiad and the experimental one. It tells you how to correctly formulate any Olympiad problem so as not to lose points.
- Typical tasks of the theoretical round
- Experimental tasks at Olympiads
- Recommendations for formatting tasks and planning time
Statics and hydrostatics
The Rule of Moments, which is the basic law in statics, is introduced and described in detail, and it is also explained how and why levers should be used. All basic concepts in hydrostatics are covered in depth.
- Moment of power. Rule of moments. Body equilibrium conditions
- Center of gravity of the body
- Addition of forces
- Levers
- Hydrostatic pressure. Pascal's law. Atmosphere pressure
- Communicating vessels. Hydraulic Press
- Solving problems with changing the liquid level in a vessel
- Archimedes' Law
- Tasks with variable density
- Experiments with hydrostatic elements
Work and energy. Simple mechanisms
The basis of this section is the topic of work and energy. We talk about an unusual method of solving problems - the method of virtual movements.
- Mechanical work
- Conservative and non-conservative forces
- Energy
- Law of conservation of mechanical energy
- Virtual movement method
- Simple mechanisms. Efficiency of simple mechanisms
- The golden rule of mechanics
Charting culture
It describes in detail how and why graphs are used in physics, and why it is important to construct them correctly to solve a particular problem.
- Graphs in physics
- Construction rules
- Typical errors during construction
