Gravity

Question 1

Free fall acceleration of gravity

Answer 1

~10m/s(2)

(use 9.8 m/s(2) if asked)

Question 2

What is terminal velocity?

Answer 2

Eventually the air resistance acting upwards on the objects equals the weight acting downwards. The overall force on the object is balance or zero; it therefore cannot accelerate and continues to fall at constant velocity. This is referred to as the terminal velocity.
