Linear momentum (p) is defined as the product of mass (m) and velocity (v), represented by the formula p = mv. The symbol 'p' comes from the word 'impetus'.
The standard unit for mass is kilograms (kg) and for velocity is meters per second (m/s). Therefore, the unit for linear momentum is kilogram meters per second (kg m/s).
The video introduces linear momentum, differentiating it from angular momentum, which is associated with spinning objects. Linear momentum applies to objects moving in a straight line.
The video demonstrates calculating the linear momentum of a Ferrari with a mass of 1485 kg moving at 325 km/h. First, the velocity is converted to meters per second (approximately 90 m/s). The momentum is then calculated as 133,650 kg m/s, which is expressed in standard form as 1.34 x 10^5 kg m/s.
