To solve for the magnitude of force exerted on the given object, use this formula:Īfter calculating with these formulas, you get the following results: While the equation to find the final momentum is: Therefore, the equation to find the initial momentum is: The time taken by the object to accelerate is t = 6 s. The mass of the given object is m = 100 kg. The final velocity of the given object is v = 8 m/s. The initial velocity of the given object is u = 5 m/s. Also, let’s solve for the magnitude of force exerted on this object. With this information, let’s find the initial and final momentum of this object. For this example, let’s say that a given object with a mass of 100 kg gets uniformly accelerated from an initial velocity of 5 m s−1 to 8 m s−1 in a period of 6 seconds. To make this easier for you to understand, let’s use an example to illustrate how to find the initial and final momentum without using the momentum calculator. How do you find the initial and final momentum? So it can perform the different calculations to give you the results you need. This is why the calculator requires you to input several values. For these values, the momentum calculator uses the formula J = F * t.

Finally, if you know the value of the force acting on the object, enter the values of the time change and the force.

You use these values in a different computation using the formula J = m * Δv.

Second, you can enter the values of velocity change and mass of a given object.

Input these values in the change in momentum calculator to get the value you need for J = Δp.

First, you need to acquire the values of the initial momentum and final momentum.

But if you want to learn the different ways to calculate impulse: If you’ve performed manual computation using either the impulse or momentum formula, you can check your answers using the momentum and impulse calculator. The unit of both impulse and momentum is newton-seconds with a symbol “Ns.” In SI units, you express this unit as kg*m/s.

There is a simpler formula for impulse which indicates it as the product of force “F” and time “t” acting on a given body.

Learning about momentum is essential because this has several practical applications. J = Δp = p₂ – p₁ = m * v₂ – m * v₁ = m * Δvĭelta with the symbol Δ means “change.” For instance, although p refers to the instantaneous momentum, Δp represents the momentum change which happened over a specific period of time. We call any change which occurs in a body’s momentum impulse “J” with the formula: By definition, momentum “p” is a vector which is the product of the velocity “v” and the mass “m” of any given object. How to calculate momentum?īefore using this momentum calculator, you must understand what momentum is first. This calculator gives you the values of the Impulse, Initial Momentum, and Final Momentum. After entering all of these values, the impulse and momentum calculator automatically generates the results for you.Finally, enter the value of the Time Change and choose the unit of measurement from the drop-down menu.Then enter the value of the Force and choose the unit of measurement from the drop-down menu.After that, enter the value of the Mass and choose the unit of measurement from the drop-down menu.Then enter the value of the Final Velocity and choose the unit of measurement from the drop-down menu.Next, enter the value of the Initial Velocity and choose the unit of measurement from the drop-down menu.First, enter the value of the Velocity Change and choose the unit of measurement from the drop-down menu.As long as you have the values and you input them in the proper fields, the change in momentum calculator does the work for you. Although this momentum and impulse calculator requires a lot of values, it’s still very easy to work with.
