## Uniform movement of the body around the circle

Movement along a circle always occurs with acceleration and is curved, since the distance is not equal to the displacement and the trajectory occurs along a circle. The speed when

## Movement of a body thrown at an angle to the horizon

The movement of a body thrown at an angle to the horizon moves along a parabola. The maximum flight range of a body thrown at an angle to the horizon

## Newton’s law

Newton’s first law (the law of inertia) The body keeps its speed constant (uniform rectilinear motion v=const, a=0) or is at rest while the body is not affected by external

## Mechanical operation and power

Mechanical work The mechanical work W (scalar value) is found by the formula: W = $\overrightarrow{F}$·$\overrightarrow{r}$·cosΘ $\overrightarrow{F}$ — force, N; $\overrightarrow{r}$ — movement, m. when Θ=900, W=0. Mechanical work is

## Law of gravity

The law of universal gravitation was discovered by Isaac Newton in 1867. Gravitational force is the force with which material points of different mass and distance from each other are

## Law of conservation of momentum of the formula

Momentum is a vector quantity (denoted $\overrightarrow{p}$) equal to the product of mass at speed and is defined by the formula: Law of conservation of momentum in a closed system
