Terminal velocity

Question 1

what is terminal velocity?

Answer 1

the highest velocity (point on a graph) achieved by an object as it falls through a fluid or gas

Question 2

terminal velocity =

Answer 2

highest velocity/speed

Question 3

Answer 3

3

Question 4

what is stage 1 of when before an object hits the ground?

Answer 4

a resultant force acting downwards

Question 5

why do objects fall?

Answer 5

the objects weight and gravity

Question 6

what does the speed do when an object falls?

Answer 6

accelerate

Question 7

what is stage 2 of when before an object hits the ground?

Answer 7

the air resistance occurs

Question 8

what is stage 3 of when before an object hits the ground?

Answer 8

the forces are balanced

Question 9

is there air resistance in stage 1?

Answer 9

no

Question 10

Answer 10

less

Question 11

what happens to the weight and air resistance in stage 3?

Answer 11

they balance out

Answer 15

no

Question 16

what is resultant force?

Answer 16

the difference between the weight and air resistance

Question 17
