Vectors are a great help when you have to represent different physical magnitudes.

The educational resource shows information about the kinetic energy: the kinetic energy of an object is its capacity to change its environment, because it is moving. How far will two balls with different masses and velocities penetrate a block of snow?

The educational resource shows a visual about the free fall in vacuum: whatever their shape and mass, all bodies fall with the same speed in a vacuum.

The educational resource shows a visual about the free fall in air: when a body falls through a fluid such as air, its shape is important.

Concept of instantaneous velocity

Concept of displacement vector (I)

Concep of doppler effect.

This teaching unit aims at introducing vectors into the study of movement. There is a revision of the concepts of : Reference system, position and displacement vectors, presented in the 4th year of secondary education (Trajectory) There is a return to fundamental concepts like UM, AUM, UCM presented in previous courses: 2nd year of secondary education:Kinematics; 4th year of secondary education: Rectilinear Movement. and Uniform Circular Movement. Concepts like average and instantaneous veloc...
