Terminal Velocity

Question 1

Terminal Velocity

Answer 1

When the velocity of an object remains constant.

It is not accelerating nor decelerating.

Question 2

Example: When a person jumps out a plane.

1.Within 1 second.

Answer 2

The only force acting on them is their weight.

They will accelerate downwards.

Question 3

2. Within 10 seconds

Answer 3

Air resistance starts to affect the persons speed.
Both surface area and their velocity matter.
They start to decelerate.

Question 4

3. Constant velocity.

Answer 4

The person’s weight is equal to the air resistance acting on them.
The rate of acceleration decreases but they still fall downwards.
They have reached terminal velocity.

Question 5

4. When they open the parachute.

Answer 5

The surface are will increase so the air resistance will increase.
They decelerate downwards but they will still fall downwards.
Velocity decreases.

Question 6

5. Constant velocity 2

Answer 6

The air resistance and weight eventually equal out.
They reach terminal velocity.
It is much lower as their velocity is much lower.
