1 Kinematics & Dynamics

Question 1

linear motion

Answer 1

velocity and acceleration along line of motion (one-dimensional)

Question 2

linear motion equations

Answer 2

VAT:
v = v(0) + at

VAX:
v^2 = v(0)^2 + 2ax

TAX:
x = v(0)t + (at^2 / 2)

Question 3

average velocity with uniform acceleration

Answer 3

x = vt

Question 4

projectile motion

Answer 4

2-dimensional motion

motion in each plane analyzed independently

Question 5

projectile motion equations

Answer 5

v(y) = v sin(theta)
v(x) = v cos(theta)

Question 6

inclined planes

Answer 6

one-dimensional, but not in the same direction as largest force (gravity)

F(parallel) = mg sin(theta)
F(N) = mg cos(theta)
if angle of incline is known

Question 7

circular motion equations

Answer 7

F(c) = mv^2 / r
a(c) = v^2 / r

Question 8

dynamics =

Answer 8

forces and torques

Question 9

translational equilibrium

Answer 9

vector sum of all forces = 0

constant speed and direction (velocity) NOT sitting still

Question 10

rotational equilibrium

Answer 10

torque (instead of force)
equal and opposite torques

pivot point = fulcrum

T = rF sin(theta)
