What I Can Do
Analyze the following situations. Infer what will happen in the following situations.
Write your answers in complete sentences. Use a separate sheet of paper.
1. What will happen when a hammer and a feather are dropped at the same time and
height? (air resistance is negligible)
2. What will happen when two balls of the same mass but different volumes are dropped at
the same time from the top of a tall ladder? Which will hit the ground first? Why?
3. What will happen when two balls of different masses but same volume are dropped
from that same ladder? Which will hit the ground first? Why?

Answer:
1. the hammer are the first who hit the ground while feather is take a long time because feather have air resistance
2 since the Gravitational force is equal on all the bodies. Also volume is inversely proportonal to density for constant mass, so the body will experience greater effect of air resistance,this decreases the velocity of fall and prolongs the time required to hit the ground.
3.When you drop a ball (or anything) it falls down. Gravity causes everything to fall at the same speed. This is why balls that weigh different amounts hit the ground at the same time. Gravity is the force acting in a downwards direction, but air resistance acts in an upwards direction.
