Which of the following was/were used by the Greek philosophers in order to understand the world?
a Observation
b Experiment
C Reason
d All of the above

Need help

a and c are both correct

Explanation:

The Greek Philosophers had to reject many existing explanations (mostly from the babylonians and the egyptians) because of possible religion bias. They resorted to logic and reason to provide understanding for the world around them. The first set of Greek Philosophers were the Milesian thinkers; whom aside from logic and reason also placed value on Observation in understanding the world.

There are generally no evidence to support the use of experiment to support the claims of the Greek philosophers

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
