What evidence did sir issac newton use to support his particle explanation of light

This question is totally off base and out in left field.
Isaac Newton never had a particle explanation of light.
The notion of light as a stream of particles was never proposed
until more than 100 years after Newton's death.
In 1905, shortly after the concept was invented mathematically,
Einstein used it to explain the 'photoelectric effect', for which he
won the 1921 Nobel Prize in Physics (his one and only Nobel).

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

No because scientist are still changing there mines today so they are not correct to this day
