![]() Momentum is determined by the product of the mass of the object and its velocity. The everyday meaning of momentum is relatively consistent with its specific meaning, regardless of the type of momentum. That is because the truck’s force is higher than yours. however, if you hit by truck which has higher linear momentum because of its high weight, you will be lucky to survive. ![]() For example, if you are running forward and dog runs into you by accident, your trajectory will be changed, and you may fall however you should not be hurt too badly because the momentum of the dog was similar to yours. An outside object, with its own force can change the trajectory of an object with a linear momentum. It is also known as force, which is the quantity of mass associated with a body that moves along a straight path. For example, planetary bodies such as Earth have a first momentum that is calculated from the result of its motion in relation to the Sun and then an additional momentum calculated from the velocity of its spin on its own axis. This means that a single body can have two types of angular momentum. It is obtained by multiplying a body’s mass by its angular velocity. Types of momentumĭepending upon the nature of motion momentum can be described in following major types, And if person stands by the side of the road, the momentum of the truck relative to that person is 20,000 kgm/s northward. If the truck is driven, then the momentum of the truck is relative to the body of the person driving the truck which is zero. Momentum is directly proportional to the velocity, let us take a 1,000-kg truck moving at 20m/s with respect to the surface of a highway, travelling northward. This principle can be better understood by the following example, Thus, the above equation can be rewritten as:Īlthough the direction of the momentum can be expressed in various ways, depending on the number of dimensions involved, it is stated that the “direction of momentum is same as the direction of velocity”. In physics, the symbol of the quantity momentum is the lower case p.
