In Newtonian mechanics linear momentum translational momentum or simply momentum (pl. momenta) is the product of the mass and velocity of an object. It is a vector quantity possessing a magnitude and a direction. If m is an object’ s mass and v is its velocity (also a vector quantity) then the object’ s momentum is: =. In SI units momentum is measured in kilogram meters per second ( kg ⋅ m/s ).

Mass ( kg ) Speed ( m/s ) Momentum (N⋅ s ) Explanation 0.42 2. 4 1 A 420-gram (15 oz) football (FIFA specified weight for outdoor size 5) kicked to a speed of 8.6 km/h (5.3 mph). 0.42 38 16 The momentum of the famous football kick of the Brazilian player Roberto Carlos in the match against France in 1997. The football had a speed of 137 km/h (85 mph …

Angular momentum is a vector quantity (more precisely a pseudovector) that represents the product of a body’ s rotational inertia and rotational velocity (in radians/sec) about a particular axis. However if the particle’ s trajectory lies in a single plane it is sufficient to discard the vector nature of angular momentum and treat it as a scalar (more precisely a pseudoscalar).

Definition. An electronvolt is the amount of kinetic energy gained or lost by a single electron accelerating from rest through an electric potential difference of one volt in vacuum. Hence it has a value of one volt 1 J/C multiplied by the electron’ s elementary charge e 1.602 176 634 × 10 −19 C. Therefore one electronvolt i…
