Accelerating (5.1) p 178

#### Slide 1 -Slide

Lesson goals:
• Understand the velocity-time graph (v,t)
• Use the formula for acceleration
• Use the (v,t)-diagram to calculate distance/ displacement

#### Slide 2 -Slide

drawing a (v,t)-diagram
v - vertical axis
t - horizontal axis

0-4 s Velocity increases therefore
the object is accelerating
after 4s the motion is constant
uniform motion

#### Slide 3 -Slide

Acceleration
An object has a constant acceleration if there is a uniform increase in velocity, for example
t = 1s then v = 3 m/s,
t = 2s then v= 6 m/s
t = 3s then v = 9 m/s
therefore the acceleration is 3 m/s2

#### Slide 4 -Slide

Calculating velocity:

v - velocity in m/s
s - distance in m
t - time in s
v=ΔtΔx
Δx=xfinalxinitial

#### Slide 5 -Slide

Calculating acceleration:

a - acceleration in m/s2
t - time in s
v - velocity in m/s
a=ΔtΔv
Δv=vfinalvinitial

#### Slide 6 -Slide

convert velocity
velocity is often given in km/h and must be converted to m/s

#### Slide 14 -Quiz

Calculating displacement
You can use the (v,t)-diagram
to calculate distance

Distance = area under the graph
