Oct 11, 2023 · Momentum Equation for these Calculations: p = mv p = m v. Where: p = momentum. m = mass. v = velocity. The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v). The calculator can use any two of the values to calculate the third. Along with values, enter the known units of measure for each and this ...

Impulse is change in momentum. Δ is the symbol for "change in", so: Impulse is Δp Force can be calculated from the change in momentum over time (called the "time rate of change" of momentum): F = Δp Δt
We can rearrange: F = Δp Δt Into: Δp = F Δt So we can calculate the Impulse (the change in momentum) from force applied for a period of time.
Conserved: the total stays the same (within a closed system). Closed System: where nothing transfers in or out, and no external force acts on it. Note: At an atomic level Mass and Energy can be converted via E=mc2, but nothing gets lost.
Momentum is a vector: it has size AND direction. Sometimes we don't mention the direction, but other times it is important!
It may not seem like much, but since they can weigh anywhere between 2 t 2 \text{ t} 2 t to 7 t 7 \text{ t} 7 t, they can gain tremendous momentum of about 70 t⋅km/h 70 \text{ t⋅km/h} 70 t⋅km/h (19.4 kN⋅s) to 245 t⋅km/h 245 \text{ t⋅km/h} 245 t⋅km/h (68.1 kN⋅s) in their charge. So you can see why it’s wiser to get out of dodge.
In Scientific Notation. 25 kilometers per hour. = 2.5 x 10 1 kilometers per hour. ≈ 6.94444 x 10 0 meters per second.

The SI units of momentum are kg·m/s or N·s, and imperial units are lbs·ft/s. Mass is a scalar, and velocity is a vector quantity.
It describes how quickly or slowly an object moves from one place to another. The standard (SI) unit of speed is meters per second (m/s), but it can also be expressed in other units, such as kilometers per hour (km/h), miles per hour (mph), or feet per second (ft/s), depending on the context or the country's measurement system.
