Motion and Force Flashcards
1
Q
Relate V and Vo
A
V = Vo + at
- Vevo Tat
2
Q
Circumference and radius relation
A
C = 2πr
3
Q
Centripetal acceleration
A
a = v^2/r
4
Q
Centripetal force
A
F = ma F = mv^2/r
5
Q
Four fundamental forces
A
Gravity
6
Q
Strong force
A
Prevents protons from repulsing each other at very small distances (nucleus)
7
Q
Relate x, t, Vo, V
A
x = 1/2(V + Vo)t
8
Q
Relate x, a, Vo, t
A
∆x = Vot + (1/2)at^2
Delx is Vot halfatoo
9
Q
Relate x, a, Vo, V
A
V^2 = Vo^2 + 2a(∆x)
- Veetu me Votu tuax
10
Q
Relate V and Vo
A
Vavg = 1/2 (V + Vo)
11
Q
Relate V and h
A
V = √2gh
- Vo must be 0
- V = Root tugghh
12
Q
Magnitude of spring force
A
F = kx
13
Q
Torque
A
T = Fl
T = Fsin(theta)d
14
Q
How does a pulley change the force required to do a given amount of work?
A
Pulley halves the force required
15
Q
If distance of force from pivot point is twice that of load from pivot point, lever will ____ the force required
A
Halve the force required
