§4.3 Acceleration

p. 172-175
ex 22-29 p 176-191

#### Slide 3 -Tekstslide

§4.3 - Learning Goals:
• I can describe the concept of acceleration and understand which measurements and units are necessary to calculate it.
• I can calculate the acceleration of an object using the acceleration formula.
• I can create and interpret v,t-diagrams relating to an object’s change in motion.
• I can use an object’s resultant force to determine what type of motion it has.

P.172-175

§4.3 - Keywords:
• Acceleration
• Deceleration
• v,t-diagram

P.172-175

#### Slide 5 -Tekstslide

What is acceleration?
Acceleration is change in speed, so speeding up or slowing down, measured in meters per second squared (m/s2).
It is calculated by:
P.172-175

#### Slide 6 -Tekstslide

What is acceleration?
P.172-175

#### Slide 7 -Tekstslide

What is deceleration?
Deceleration occurs when an object’s speed decreases, in other words, a negative acceleration.

P.172-175

#### Slide 8 -Tekstslide

Uniform motion
Uniform motion - When the speed stays constant

P.172-175

#### Slide 9 -Tekstslide

Acceleration
Acceleration: speed increases→ Graph gets steeper

P.172-175

#### Slide 10 -Tekstslide

Deceleration
Deceleration: speed decreases → Graph gets flatter

P.172-175

#### Slide 11 -Tekstslide

Let's practice:
P.172-175
A car is accelerating for 8 seconds, increasing by 20 m/s every second. Complete the following table, then make an v,t diagram of your results.

#### Slide 12 -Tekstslide

Let's practice:
P.172-175
A car is accelerating for 8 seconds, increasing by 20 m/s every second. Complete the following table, then make an v,t diagram of your results.

#### Slide 13 -Tekstslide

Let's practice
Now make make an x,t diagram of your results
