The dimension of momentum is kilogram-meter per second (kg⋅m/s). This describes the physical quantities that define momentum.
Momentum (p) is a measure of an object's mass in motion. It is calculated as the product of an object's mass (m) and its velocity (v):
p = m * v
Where:
- p represents momentum
- m represents mass, measured in kilograms (kg)
- v represents velocity, measured in meters per second (m/s)
Therefore, the dimension of momentum combines the dimension of mass (kg) and the dimension of velocity (m/s), resulting in kg⋅m/s. This unit signifies how much "oomph" a moving object possesses. A heavier object moving at the same speed as a lighter object will have more momentum, as will an object moving faster than an identical object.
