Terminal Velocity

Question 1

Why do falling objects fall fast?

Answer 1

The force of gravity is much more than the frictional force slowing them down

Question 2

What happens as speed increases

Answer 2

Friction builds up

Question 3

What does the build up of friction do

Answer 3

Gradually reduces the acceleration until eventually the frictional force is equal to the accelerating force

Question 4

When does soemthing reach terminal velocity?

Answer 4

It will have reached its maximum speed or terminal velocity and will fall at a steady speed

Question 5

What does terminal velocity depend on

Answer 5

Shape and area
Typically, the less streamlined an object is, the lower its terminal velocity

Question 6

Which types of objects have lower terminal veloctiy

Answer 6

Objects with large surface area
less streamlined objects

Question 7

For example

Answer 7

For example, if you dropped a marble and beach ball off a tall building, the marbles terminal velocity would be higher than the terminal velocity of the ball
and this is because there is more air resistance acting on the beach ball at any given speed
