Resultant velocity is the total velocity of an object after taking into account its direction and magnitude. It is calculated by adding the individual velocities using vector addition.
Resultant velocity takes into account the direction and magnitude of an object's motion, while average velocity only considers the displacement and time. Resultant velocity is a vector quantity, while average velocity is a scalar quantity.
The resultant velocity of an object can be affected by changes in its direction, speed, and acceleration. External forces such as friction, air resistance, and gravity can also affect the resultant velocity.
Yes, resultant velocity can be negative if the object is moving in the opposite direction of the chosen positive direction. For example, if the positive direction is defined as going east and the object is moving west, the resultant velocity will be negative.
Resultant velocity is used in various fields such as physics, engineering, and navigation. It is used to determine the speed and direction of an object's motion, as well as to calculate the trajectory and landing location of projectiles.
