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 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.

The equation which uses s, u, v and a is v2 = u2 + 2as. This can be rearranged to make a the subject: a = v2 − u2 2s. We can now substitute in the values of the variables that we know: a = v2 − u2 2s, = 02 − 222 2 × 40, = − 6.05ms − 2. The car accelerates at − 6.05ms − 2. This is equivalent to decelerating at a rate of 6.05ms − 2.
