Why do we still use Newtonian motion if Einstein's model is better?

Answer explanation

We still use Newtonian motion because it is simpler and easier to understand than Einstein's model. Newtonian motion is still a valid model for many everyday situations, such as the motion of objects on Earth, and it is still useful for making predictions and calculations. Additionally, Einstein's model is more complex and requires more advanced mathematics to understand and apply. Therefore, Newtonian motion is still used in many areas of science and engineering.
