In the world of physics, inelastic collisions are a fundamental concept, particularly in mechanics and energy conservation. When two objects collide inelastically, they stick together after the collision, and kinetic energy is not conserved, though momentum is. In such a scenario, calculating the velocity of the combined objects after the collision is essential for understanding the impact of the event. This article will explore how to use an Inelastic Collision Velocity Calculator to determine the velocity after two objects collide inelastically.
This simple tool allows you to calculate the final velocity of two masses after an inelastic collision based on their initial velocities and masses. Whether you are a student learning about physics or an enthusiast interested in practical applications of motion, this tool can be an invaluable resource.
What is an Inelastic Collision?
An inelastic collision occurs when two objects collide, and after the impact, they move together as a single object. In such collisions, some kinetic energy is lost, typically converted into other forms of energy such as heat or sound. The key feature of an inelastic collision is that momentum is conserved, but kinetic energy is not.
Formula for Inelastic Collision Velocity
To calculate the velocity after the collision, you can use the following formula, which is derived from the principle of conservation of momentum:
V = (m1 * v1 + m2 * v2) / (m1 + m2)
Where:
- m1 = Mass of the first object
- v1 = Velocity of the first object before the collision
- m2 = Mass of the second object
- v2 = Velocity of the second object before the collision
- V = Final velocity of both objects after the collision
This equation ensures that momentum before and after the collision is balanced, which is a fundamental principle in physics.
How to Use the Inelastic Collision Velocity Calculator
Using the Inelastic Collision Velocity Calculator is a straightforward process. Here’s a step-by-step guide on how to use the tool on your website.
Step-by-Step Guide
- Enter the Mass of the First Object (m1):
- The first input field asks for the mass of the first object involved in the collision. This is typically measured in kilograms (kg).
- Enter the Velocity of the First Object (v1):
- Next, you need to input the velocity of the first object before the collision. This should be in meters per second (m/s).
- Enter the Mass of the Second Object (m2):
- The second input field requires the mass of the second object. Like the first, this should be in kilograms (kg).
- Enter the Velocity of the Second Object (v2):
- The final input field asks for the velocity of the second object before the collision. This, too, should be in meters per second (m/s).
- Calculate the Result:
- After entering all the required values, click the “Calculate” button. The tool will process the information using the inelastic collision formula and display the final velocity (V) of the two objects combined.
Example
Let’s say two objects are involved in an inelastic collision:
- Mass of the first object (m1) = 5 kg
- Velocity of the first object (v1) = 10 m/s
- Mass of the second object (m2) = 3 kg
- Velocity of the second object (v2) = 2 m/s
Using the inelastic collision formula:
V = (m1 * v1 + m2 * v2) / (m1 + m2)
Substituting the values:
V = (5 * 10 + 3 * 2) / (5 + 3)
V = (50 + 6) / 8
V = 56 / 8
V = 7 m/s
So, the final velocity after the collision is 7 m/s.

Helpful Information About Inelastic Collisions
- Types of Collisions: In addition to inelastic collisions, there are also elastic collisions, where both momentum and kinetic energy are conserved. In contrast, perfectly inelastic collisions are a special case of inelastic collisions where the objects stick together after the collision.
- Energy Loss: In an inelastic collision, the energy lost typically turns into other forms of energy, such as heat or sound, which can be important in certain engineering or scientific applications.
- Momentum Conservation: Regardless of whether the collision is elastic or inelastic, momentum is always conserved in a closed system. This principle is essential in solving collision-related problems.
- Real-World Examples: Car crashes, object interactions in sports, and even particles colliding in accelerators are real-world examples of inelastic collisions.
