Question

Why might it be necessary to ignore some of the data points just before and just after the collision?

Answer 1

In physics, some data points may need to be ignored just before and after a collision. This is done to remove errors and focus on the specific moment of collision.

Step-by-step explanation:

In physics, it may be necessary to ignore some of the data points just before and just after a collision for various reasons. One reason is to remove outliers or errors in the measurements that could skew the results. For example, if there is a sudden spike or dip in the data due to a measurement error, it would be necessary to exclude those points to ensure accurate analysis.

Another reason is to focus on the specific moment of collision. By excluding the data points surrounding the collision, it allows for a clearer observation and analysis of the collision itself. This is important for understanding the dynamics and effects of the collision.

Therefore, it is not necessary to ignore both sets of data equally, but rather selectively remove data points that may introduce errors or hinder the analysis of the collision.

Answer 2

We have no idea. We need to examine the experimental set-up. You've given us no information, except that there may have been some sort of collision.
