Impulse vs. Push
What's the Difference?
Impulse and Push are both terms that refer to a sudden force or action, but they have slightly different connotations. Impulse typically refers to a sudden urge or feeling that prompts someone to act in a certain way, often without much thought or consideration. On the other hand, Push usually implies a more deliberate and forceful action, where someone is actively pushing or exerting pressure to achieve a specific goal or outcome. While both terms involve a sudden burst of energy or force, the underlying motivations and intentions behind them can vary significantly.

Further Detail
Definition
Impulse and push are two terms that are often used interchangeably, but they actually have distinct meanings in the world of physics. Impulse refers to the change in momentum of an object, which is calculated by multiplying the force applied to the object by the time over which the force is applied. On the other hand, push is a force that is applied to an object in order to move it in a certain direction. While both impulse and push involve the application of force, they differ in terms of the specific calculations and applications.
Calculation
When it comes to calculating impulse, the formula is simple: Impulse = Force x Time. This means that the magnitude of the impulse is directly proportional to both the force applied and the time over which the force is applied. On the other hand, calculating push is a bit more straightforward, as it simply involves applying a force to an object in order to move it. Push does not involve a specific formula like impulse does, but rather relies on the application of force in a specific direction.
Application
Impulse is often used in the context of collisions, where the change in momentum of an object is crucial in determining the outcome of the collision. By calculating the impulse of the collision, scientists and engineers can better understand how the objects involved will react to the impact. Push, on the other hand, is more commonly used in everyday scenarios, such as pushing a door open or pushing a shopping cart. Push is a force that we apply in our daily lives without even realizing it.
Force
One key difference between impulse and push is the concept of force. Impulse is directly related to force, as it is calculated by multiplying force by time. This means that the greater the force applied to an object, the greater the impulse will be. Push, on the other hand, is simply a force that is applied to an object in order to move it. While force is a crucial component of both impulse and push, the way in which it is applied differs between the two concepts.
Time
Time is another important factor to consider when comparing impulse and push. In the calculation of impulse, time plays a crucial role in determining the magnitude of the impulse. The longer the force is applied to an object, the greater the impulse will be. Push, on the other hand, does not involve a specific time component. Push is simply the act of applying force to an object in order to move it, without consideration for the duration of the force application.
Conclusion
In conclusion, while impulse and push both involve the application of force, they differ in terms of calculation, application, force, and time. Impulse is calculated by multiplying force by time and is often used in the context of collisions, while push is simply the act of applying force to move an object. Understanding the differences between impulse and push can help us better grasp the concepts of force and motion in the world around us.
