2.5 terminal velocity

Question 1

drag characteristics

Answer 1

• increases as the objects speed increases
• cannot cause object to start moving or increase speed
• affected by the thickness and the shape and size of object

Question 2

terminal velocity

Answer 2

when objects driving force and opposing drag force balance each other out, resulting in constant speed

Question 3

terminal velocity three stages

Answer 3

1. objects accelerates from rest due to a constant driving force
2. as it speeds up, drag force increases, slowing down the acceleration
3. driving force n drag force become equal, leading to constant speed

Question 4

friction

Answer 4

a force that opposes the movement between two surfaces in contact
