Describe Galileo's analysis of projectile motion

Galileo Galilei was a scientist that proposed many things about projectile motion. He claimed that:

- Projectile motion was consisted of both
**horizontal and vertical components**.- He proposed that these components were:
**independent**of each other- occurred
**simultaneously** **perpendicular**to each other

- He proposed that these components were:
- Vertical acceleration was
**the same for all falling objects**if air resistance is disregarded- This was equal to the
**gravitational acceleration**of the planet ($9.8ms^{-2}$) - Attempted to prove this in a well known
**Leaning Tower of Pisa Experiment**

- This was equal to the
- Trajectory of a projectile is a
**parabola**- This made analysis much easier as many mathematical developments were known for the parabola since the Ancient Greeks.

- A motion of an object is relative to its frame of reference and
**an object has the motion of its intertial frame of refence**.- He tested this in his
**Crow's Nest experiment**- It was thought that, if a ship was moving at a constant speed, and a ball was dropped from the crows nest, it would fall
**behind**the ship and into the sea as the ship would have moved. - Instead, it fell
**straight down**onto the ship as if it hadn't moved. - This is explored later.
