Terminal Velocity

Question 1

Terminal velocity TEMPLATE (7)

Answer 1

• UNBALANCED FORCE: object has weight / downward force (due to gravity on the object)…
• so it accelerates downwards
• there is a force of drag / air resistance upwards (which opposes motion)
• drag increases as speed increases / as it accelerates
• eventually drag = weight and forces are equal…
• BALANCED FORCES: so resultant force is 0N…
• so no acceleration…
• so objects travels at constant speed
