Question

what is a line of best fit, and what does it help us to make? a straight line representing variable relationship, helps in making predictions. what else do you think that we should investigate in order to fully understand how objects have collisions? your answer whats the difference between data and evidence? your answer

Explanation:

1. A line of best - fit is a straight line that represents the relationship between variables in a scatter - plot. It helps in making predictions about the values of one variable based on the other by minimizing the sum of the squared vertical distances from the data points to the line.
2. To fully understand how objects have collisions, we could investigate factors like the mass of the objects, their initial velocities (both magnitude and direction), the type of collision (elastic or inelastic), and the forces acting during the collision.
3. Data refers to raw facts, numbers, or observations. Evidence is data that has been analyzed, interpreted, and is used to support or refute a claim or hypothesis.

Answer:

1. A line of best - fit is a straight line representing variable relationship and helps in making predictions.
2. Investigate mass, initial velocities, type of collision, and forces acting during collision.
3. Data is raw facts/numbers/observations; evidence is analyzed data for claims.
