Momentum (4 of 16) Force vs Time Graph  Summary and Q&A
TL;DR
This video explains how to determine impulse from a forcetime graph and how it relates to the change in momentum and velocity of an object.
Key Insights
 ⌛ The area under a forcetime graph represents the impulse experienced by an object.
 💁 Calculating the impulse involves finding the areas of different shapes formed by the graph.
 Impulse is equal to the change in momentum of an object.
 💱 The change in momentum can be calculated using the formula: change in momentum = mass × change in velocity.
 👻 Knowing the initial velocity, final velocity, and change in velocity allows for determining the direction of the force applied.
 🇦🇪 Units for impulse are Newton seconds, while units for momentum are kilogram meters per second.
 ⌛ The area under a forcetime graph can be separated into different sections to calculate individual impulses.

Questions & Answers
Q: What does the area under a forcetime graph represent?
The area under a forcetime graph represents the impulse, which is equal to the change in momentum of an object.
Q: How is the impulse calculated for the first 4 seconds?
The impulse for the first 4 seconds is calculated by finding the area of a triangle, with 4 seconds as the base and 40 Newtons as the height.
Q: How is the impulse calculated for the interval from 4 to 10 seconds?
The impulse for the interval from 4 to 10 seconds is determined by finding the area of a rectangle, with 6 seconds as the base and 40 Newtons as the height.
Q: What is the relationship between impulse and change in momentum?
According to the momentumimpulse equation, impulse is equal to the change in momentum of an object.
Summary & Key Takeaways

The video discusses a force versus time graph and how to find the impulse by calculating the area under the graph.

The impulse from 0 to 4 seconds is determined by finding the area of a triangle, and the impulse from 4 to 10 seconds is found by calculating the area of a rectangle.

The total impulse is then calculated by adding the impulses from both sections.
