Why is the speed of objects increasing during free fall?

• They are getting heaver

• They are changing the shape

• The gravity is pulling them down

• There is no air resistance

  The left diver will have

• Greater acceleration because more gravity acting on him

• The same gravity acting on him as on the other diver

• different gravity from the other diver IF they have different mass

• less air resistance due to greater surface area
