Kinematics Flashcards
1
Q
What are the 4 equations
A
Vf=vi+at
Vf2 = vi2 +2ad
D=vit + 1/2 at2
D= (vi+vf/ 2) xt
2
Q
Can you use the kinematic equation when a=0
A
No only if a is constant
3
Q
What can you use if a isn’t constant
A
V=d/t
A=v/t
You can also plot a graph and use are for d it graph is vt
4
Q
At the moment a car is passing anothe their d values are equal true or false?
A
True you and make the equations equal to each other and solve using both sides values
5
Q
What is acceleration due to gravity
A
-9.81
6
Q
Do you devide or multiply when going from km/h to m/s
A
Divide
7
Q
How do you go from m/s to km/ h
A
Multiply by 3.6
8
Q
Why 3.6
A
Cause there is 3600 seconds in an hour and 100m in a km
9
Q
A
