Here is how the Change in Momentum equation looks like.

1260 = 12.6 \cdot (250 - 150)

1260kg*m/s = 12.6kg \cdot (250m/s - 150m/s)

1260 = 12.6 \cdot (250 - 150)

Change in Momentum Solution

Follow our step by step solution on how to calculate Change in Momentum?

FIRST Step Consider the formula

ΔU = M \cdot (u 02 - u 01)

Next Step Substitute values of Variables

∴

ΔU = 12.6kg \cdot (250m/s - 150m/s)

Next Step Prepare to Evaluate

∴

ΔU = 12.6 \cdot (250 - 150)

LAST Step Evaluate

∴

ΔU = 1260kg*m/s

How to Evaluate Change in Momentum?

Change in Momentum evaluator uses Change in Momentum = Mass of Body*(Initial Velocity at Point 2-Initial Velocity at Point 1) to evaluate the Change in Momentum, Change in Momentum formula is defined as the measure of the difference in momentum of an object before and after an event, reflecting the impact of forces acting on the object during that time interval. Change in Momentum is denoted by ΔU symbol.

How to evaluate Change in Momentum using this online evaluator? To use this online evaluator for Change in Momentum, enter Mass of Body (M), Initial Velocity at Point 2 (u₀₂) & Initial Velocity at Point 1 (u₀₁) and hit the calculate button.

FAQs on Change in Momentum

What is the formula to find Change in Momentum?

The formula of Change in Momentum is expressed as Change in Momentum = Mass of Body*(Initial Velocity at Point 2-Initial Velocity at Point 1). Here is an example- 1260 = 12.6*(250-150).

How to calculate Change in Momentum?

With Mass of Body (M), Initial Velocity at Point 2 (u₀₂) & Initial Velocity at Point 1 (u₀₁) we can find Change in Momentum using the formula - Change in Momentum = Mass of Body*(Initial Velocity at Point 2-Initial Velocity at Point 1).

Can the Change in Momentum be negative?

No, the Change in Momentum, measured in Momentum cannot be negative.

Which unit is used to measure Change in Momentum?

Change in Momentum is usually measured using the Kilogram Meter per Second[kg*m/s] for Momentum. Gram Centimeter per Second[kg*m/s], Dyne Hour[kg*m/s], Kilonewton Minute[kg*m/s] are the few other units in which Change in Momentum can be measured.
