acceleration due to gravity

Question 1

in a vacuum, all objects accelerate towards the Earth at ____ regardless of their ___: by who?

Answer 1

• at the same rate
• mass
• by galileo

Question 2

air resistance

Answer 2

• slows rate at which objects fall
• depends on surface area

Question 3

terminal velocity

Answer 3

constant velocity
- e.g. u reach constant falling rate when skydiving

Question 4

when do u reach terminal velocity

Answer 4

when given enough time to fall, where air resistance balances w/ gravity

Question 5

without air resistance, if an object is thrown in the air..

Answer 5

• it will fall at the same rate as rise
• initial and final velocities have same magnitude but diff. directions
