Change In Momentum Calculator
To find change in momentum, subtract the initial velocity from the final velocity, then multiply by the mass.
This calculator helps you find how much momentum changes when an object speeds up or slows down. Momentum is the motion an object has, and when its velocity changes, so does its momentum.
This tool is useful for students, physics learners, and engineers who study collisions, forces, and motion. Instead of solving equations by hand, just enter the values, and the calculator will give the answer instantly.
Formula:
The formula for change in momentum is:
| Symbol | Meaning |
|---|---|
| Δp | Change in Momentum (kg·m/s) |
| Vf | Final Velocity (m/s) |
| Vi | Initial Velocity (m/s) |
| m | Mass (kg) |
What is Change in Momentum?
Change in momentum happens when an object gains or loses speed. It depends on how fast the object was moving before and after and its mass.
For example, if a car moves at 10 m/s and then speeds up to 20 m/s, the momentum changes based on the car’s mass and speed difference. This concept is used in sports, vehicle safety, and space travel, where momentum plays a big role in motion and collisions.
Understanding change in momentum helps in physics and engineering when studying collisions, force, and acceleration.
Final Words:
Simply put, momentum changes when an object’s speed increases or decreases. This calculator makes it quick and easy to find how much momentum changes in physics and real-world situations.
FAQs:
1. How to calculate change in momentum?
Use the formula: Δp = (Vf – Vi) × m, where Vf is final velocity, Vi is initial velocity, and m is mass.
2. What is the change in momentum of a 1500 kg car when its speed increases from 36 to 72 km/h?
Convert speeds to m/s, then use the formula Δp = (Vf – Vi) × m to find the change in momentum.
3. What is impulse in momentum?
Impulse is force applied over time, which also changes momentum. It follows the impulse-momentum theorem.
