To calculate common velocity, step one is to find out the whole distance traveled by the article. This entails figuring out the preliminary place of the article and its closing place after a sure time interval.
The space traveled is the magnitude of the displacement, which is the change in place of the article. It’s a scalar amount, that means it has solely magnitude and no course. To seek out the whole distance traveled, you need to use the next steps:
- Establish the preliminary and closing positions: Decide the place to begin and ending level of the article’s movement. These positions might be represented by vectors or coordinates in a coordinate system.
- Calculate the displacement: Subtract the preliminary place vector from the ultimate place vector. This operation leads to a vector that represents the displacement of the article.
- Discover the magnitude of the displacement: The magnitude of the displacement vector is the whole distance traveled by the article. It may be calculated utilizing the Pythagorean theorem if the displacement vector is in two dimensions or by merely taking absolutely the worth of the displacement whether it is in a single dimension.
Upon getting decided the whole distance traveled, you’ll be able to proceed to the subsequent step of calculating common velocity.
