Saya mau tau where: dari Moméntum. Jelaskan dalam bahasa sunda

Example: a modél airplane of 1 kg travelling due north at 1 m/s in straight and level flight has a momentum of 1 kg m/s due north méasured from the ground. To the dummy pilot in the cockpit it has a velocity and momentum of zero.

According to Newton's second law the rate of change of the momentum of a particle is proportional to the resultant force acting on the particle and is in the direction of that force. In the case of constant mass, and velocities much less than the speed of light, this definition results in the equation
