Terminal Velocity + Netwon's 1 + 2

Question 1

terminal velocity

Answer 1

velocity is constant, resultant force is 0

Question 2

drag

Answer 2

collision between an object and air particles

Question 3

falling process

Answer 3

weight is larger than air resistance (accelerates down), acceleration increases (increasing air resistance), air resistance = weight (terminal velocity)

Question 4

parachute role

Answer 4

increase surface area, increases drag effect, slows down, terminal velocity

Question 5

newton’s 1st law

Answer 5

force = mass x acceleration, size of resultant force is proportional to acceleration caused

Question 6

newton’s 2nd law

Answer 6

resultant force is required to change an object’s motion, remains stationary or moves with same velocity
