Movimiento en dos o tres dimensiones
Vectores de posición y desplazamiento
To describe the motion of an object, one should first be able to describe its position (where it is at any particular time). More precisely, the position ...
Vectores de velocidad media e instantánea
To calculate other physical quantities in kinematics, the time variable must be introduced. The time variable not only allows us to state where an object ...
Vectores de aceleración
In everyday conversation, accelerating means speeding up. Acceleration is a vector in the same direction as the change in velocity, Δv, therefore the ...
Dirección de los vectores de aceleración
Acceleration occurs when velocity changes in magnitude (an increase or decrease in speed), direction, or both. Although acceleration is in the direction ...
Movimiento de proyectiles
An object thrown in the air follows a parabolic path under the influence of Earth's gravitational force. The motion of such an object is called ...
Movimiento de un proyectil: ecuaciones
Projectile motion is commonly observed in our day-to-day life. For example, a basketball thrown by a player, an arrow shot from a bow, and kids jumping ...
Movimiento de una proyectil: ejemplo
The theory of projectile motion is very useful for players of several sports to improve their performance. For example, a javelin thrower needs to throw ...
Movimiento circular uniforme
Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller ...
Movimiento circular uniformemente acelerado
In uniform circular motion, the particle executing circular motion has a constant speed, and the circle is at a fixed radius. However, not all ...
Velocidad relativa en una dimensión
The understanding of the concept of reference frames is essential to discuss relative motion in one or more dimensions. When we say that an object has a ...
Velocidad relativa en dos dimensiones
Relative velocity is the velocity of an object as observed from a particular reference frame, or the velocity of one reference frame with respect to ...
