Kinematics

Is the branch of mechanics that describes the characteristics of the movement.

Kinematics Movement and trajectory

Velocity

Acceleration

Speed

Speed is how fast something moves. It's a measure of how quickly an object changes its position over a certain amount of time. Speed can be calculated by dividing the distance traveled by the time it takes to travel that distance.

Velocity is similar to speed, but it also includes the direction of motion. It tells us not only how fast something is moving, but also in which direction. So, while speed is just the rate of change of distance, velocity is the rate of change of displacement (which includes direction) over time.

Acceleration is the rate at which an object's velocity changes over time. It occurs when an object speeds up, slows down, or changes direction. So, if an object is moving faster and faster, it's accelerating positively; if it's slowing down, it's accelerating negatively or decelerating.

Speed and Average Velocity

Vectors

Vectors are quantities that have both magnitude (size) and direction. In simpler terms, they are like arrows that show both how far something goes and in which way it's going.

2D Kinematics

In 2D kinematics, we study the motion of objects in two dimensions, typically represented on a coordinate plane. We deal with motion both horizontally (along the x-axis) and vertically (along the y-axis).

This means we can analyze how fast it's moving side to side and up and down separately.
