Slide 1 - Slide

Plan for today

1. Refreshing paragraph 2

2. Discussing the homework

3. Calculations with varying speed

4. Working on the exercises in the book (Ex. 10)

Slide 2 - Slide

Learning objectives

You can calculate the average speed from a speed-time-diagram with uniform acceleration/decelaration.
You can calculate the distance covered in a diagram with uniform accelaration/decelaration.

Slide 3 - Slide

What is the formula for the speed?

v = t/s

v = m/s

v = s/t

v = s*t

Slide 4 - Quiz

10 m/s = ... km/h

3,6

10 000

2,8

Slide 5 - Quiz

Homework

1, 2, 4, 5, 8, 9

Slide 7 - Slide

A graph of the speed

On the y-axis (vertical), we put the speed.

On the x-axis (horizontal), we put the time.

So what would constant speed look like?

Slide 8 - Slide

A graph of the speed

Constant speed, means that v stays the same all the time!

Slide 9 - Slide

A graph of the speed

Constant speed, means that v stays the same all the time!

How much distance is travelled here?

Slide 10 - Slide

How much distance is travelled?

Slide 11 - Open question

A graph of the speed

How can we do this here?

Slide 12 - Slide

A graph of the speed

How can we do this here?

--> We use the average

speed

Slide 13 - Slide

How can we do this here?

--> We use the average

speed

How can we calculate the average speed here?

Slide 14 - Slide

A graph of the speed

How can we do this here?

--> We use the average

speed

How can we calculate the average speed here?

v^{​ a v g ​ ​} = \frac{​ v ^{​ i n i t ​ ​} + v ^{​ f i n a l ​ ​} ​ ​}{​ 2 ​}
