## 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

## 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

## 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

## 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;

Momentum is a vector quantity (denoted $\overrightarrow{p}$) equal to the product of mass at speed and is defined by the
