Linear motion with constant velocity and linear motion with variable velocity
how to establish the distance between two points using a map;
that vehicles and people move at different speeds.
to explain how motion works;
to define distance and speed;
to explain what linear motion with constant velocity and linear motion with variable velocity are, and to give examples of them.
If the speed of movement does not change, then we call this motion linear motion with constant velocitylinear motion with constant velocity. In reality, this rarely occurs. We often change our speed of movement. In such situations, we say that linear motion with variable velocitylinear motion with variable velocity occurs. It can be, for example accelerationacceleration (when we increase speed) or decelerationdeceleration (when we reduce speed).
A cyclist is moving at an average speed of 18 km/h. The cyclist's speed is...
- 18 m/s.
- 5 m/s.
- 10 m/s.
- 36 m/s.
Summary
Motion is the movement of one body relative to another body.
During motion, a distance is covered. By knowing the distance and the time in which it was covered, we can calculate the speed of movement.
Give at least two examples of linear motion with constant velocity in addition to two examples of linear motion with variable velocity.

ruch jednostajny – ruch, który odbywa się ze stałą prędkością w jednakowych odcinkach czasu
ruch opóźniony – ruch, w czasie którego prędkość stopniowo maleje
ruch przyspieszony – ruch, w czasie którego prędkość stopniowo rośnie
ruch zmienny – ruch, w którym dochodzi do zmian wartości prędkości.
