Relative velocity is the velocity of an object in relation to another object. It takes into account the motion of both objects and is measured from the perspective of one of the objects.
Relative velocity is calculated by subtracting the velocity of one object from the velocity of the other object. This can be done using vector addition or by using the formula Vr = V1 - V2, where Vr is the relative velocity, V1 is the velocity of the first object, and V2 is the velocity of the second object.
The main difference between relative velocity and absolute velocity is that relative velocity takes into account the motion of both objects, while absolute velocity is measured from a fixed reference point and does not consider the motion of other objects.
Yes, relative velocity can be negative. This occurs when the two objects are moving in opposite directions. In this case, the relative velocity will have a negative value, indicating that the objects are moving away from each other.
Relative velocity is used in various real life situations, such as in navigation, astronomy, and transportation. It is also used in sports, such as calculating the speed of a baseball in relation to the pitcher's hand or the speed of a swimmer in relation to the water.
