Slide 1 - Slide
Slide 2 - Video
Lesson goals:
Understand the velocity-time graph (v,t)
Use the formula for acceleration
Use the (v,t)-diagram to calculate distance/ displacement
Slide 3 - 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 4 - 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 6 m/s then v= 9 m/s
t = 3s then v = 3 m/s
therefore the acceleration is 3 m/s2
Slide 5 - Slide
Calculating velocity:
v - velocity in m/s
x - position im m
t - time in s
v=ΔtΔx
Δx=xfinal−xinitial

Slide 6 - Slide
Calculating acceleration:
a - acceleration in m/s2
t - time in s
v - velocity in m/s
a=ΔtΔv
Δv=vfinal−vinitial

Slide 15 - Quiz
Calculating displacement
You can use the (v,t)-diagram
to calculate distance
Distance = area under the graph
