Say hello to Yuri Kovalenok, a physics teacher that has become famous of a particular thing he does; making art out of formulas. His amazing work can be found on his Instagram account. We, however, decided to make a list of some of our favorites to share it with our readers.

7. Circular motion

Yuri Kovalenok refers to this one as ‘Centripetal acceleration and force’. He explains how this refers to an airplane executing a turn. The Instagram’s post read, ‘The aircraft makes a turn, moving in an arc of a circle with a constant speed v=360 km/h. Determine the radius R of the circle, if the body of the aircraft is rotated around the direction of flight at an angle of 10 degrees.’

6. Tsiolkovsky rocket equation

This is a mathematical equation that is used for describing the motion of the vehicles that follow the basic principle of a rocket.

5. Law of conservation of energy

Yuri Kovalenok describes the drawing, ‘In the experiment with the “dead loop” the ball of mass m is released from height h=3R (where R is the radius of the loop). With what force presses the ball in the lower and upper points of the loop?’

4. Electromagnetism

According to this illustration by Yuri Kovalenok, ‘Length of the movable conductor AB is equal to l. Its resistance is R. the resistance of the stationary conductor through which slides the conductor AB, is negligible. Perpendicular to the plane of the conductors applied magnetic field B. What force F must be applied to the conductor AB so that it moves at a constant speed v. The system of conductors is in the horizontal plane.’

3. Artificial satellite rotation

Kovalenok uses another illustration while talking about the motion of artificial satellites. He even offers a little quiz, ‘The period of rotation of the satellite around the Earth is 24 hours. Find at what altitude is the orbit of the satellite?’

2. Circular motion 2

Here’s another illustration for circular motion but this time with a car, ‘At the turn of the road radius of R=100 meters uniformly moving car. The center of gravity of the car is at the height of h= 1 m, the width of the wheels of the track of the car a=1.5 m. Determine the speed v at which the car can tip over. The car does not slide in the transverse direction.’

1. Statics

You can see a person performing some high-risk acrobatics, but this is not about the Olympics. It is about statics. The description reads, ‘Ladder length l=4 m is put to a smooth wall at an angle of 60 degrees to the floor. Maximum friction force Ffric=200 N. at what height h can a person weighing m=60 kg climb a ladder before the ladder starts to slide? The weight of the ladder can be neglected.’
