While momentum and impulse may be similar, they are not the same. They are comparable in that they use the same units, i.e. mass times velocity. They are however calculated in different ways. Learn more about the differences and similarities between impulse and momentum. To see the differences, play this physical science game.

**What is the difference between impulse and momentum? **

Two fundamental concepts in physics are momentum and impulse. Momentum refers to the change in speed, while impulse is the sum of force over time. An impulse can be described as the change of momentum between two points in time. Both are essential in physics to analyze and understand collisions. They can also be used to predict an object's impact on another object. We'll be discussing how these relate and how you can learn more about the topic.

**Momentum **

We often refer to an impulse as a way of describing an object's momentum. Because giving an object an impulse changes its momentum, This is why kicking a soccer ball will alter its momentum. To determine how much force is required to cause an object's momentum to change, plot the area under force vs.-time graph. The velocity is the quantity of force required to cause an object's momentum to change is important.

**Impulse **

Momentum is the speed at which an object or person moves. It can be measured in meters per second. Multiply the mass of an object by its velocity to calculate its momentum. These terms, along with the definition of momentum are closely related. An impulse is a change of momentum. A change in speed results from an impulse. A force must be applied for a specific period of time to change momentum.

**Generalized momentum **

Despite their similarities, momentum and impulse are very different. Both involve Newton's second law, which is the laws of motion. However, they are calculated differently. Let's examine the differences between these concepts. In essence, momentum is the result of mass and velocity. Impulse is the change in momentum over time. Impulse, unlike momentum, is not based upon an underlying physical principle but on an individual phenomenon.

**Air bags **

Airbags are used to reduce the impact force of a car collision. While the impact forces of a collision are constant, the momentum and impulse changes are not. Airbags reduce the impact forces and extend the time until the vehicle stops moving. These impacts are less severe than collisions with airbags.

Force unbalanced

An object that experiences unbalanced forces will experience an instantaneous change in its velocity and momentum. This is known as the impulse. Acceleration will be caused by the change in momentum. There are two types: a downward impulse, and a forward impulse. A forward impulse occurs when an object accelerates quickly, but does not increase in velocity.

**Vector quantities **

Forces in physics are not constant. Forces that are generated by people or engines over time build up making it difficult for us to calculate their total effects. The concept of impulse is crucial for understanding conservation and momentum. This article will discuss some terms that are used to measure these quantities. It will also help you to understand the relation between these quantities. This table highlights key facts about momentum and impulse.
