Scientific Revolution Views

• Galileo discovered objects fall at the same speed.

• Sir Isaac Newton later explained why with his laws of motion and universal gravity.

But why does a feather fall slower than a hammer?

• Because of wind resistance. If there was no air, objects would fall at a constant speed.
