• QUESTIONS BEFORE LECTURE 3

now think about these

• Why is falling motion hard to study? Give two reasons.
• How did Galileo overcome these two barriers by his leaps of logic?
• Did you think that heavier objects want to fall faster than light ones?
• Did you think that falling objects acquire their speed instantly?
• Do falling objects increase their speed proportionately to the distance they have fallen or the time they have fallen?
• What is uniform acceleration?
• What type of experiments did Galileo do to demonstrate uniform acceleration?
• What experience that you have had gives you the best visualization of uniform acceleration?
• What experience that you have had gives you the best visualization of the magnitude of g, the acceleration due to gravity?
• Give an example of a lighter object falling faster than a heavier one.
• Give an example of a falling object acquiring its terminal velocity almost instantly.
