Kinematics and Dynamics (sec 1)

Question 1

f(s)=u(s)N

Answer 1

Static friction

Question 2

f(k)=u(k)N

Answer 2

kinetic friction

Question 3

Torque=rFsin(0)

Answer 3

r=radius meters
F=force
sin(0) refers to difference between the perfect angle and the actual angle

Question 4

F(c)=(m*v^2)/r

Answer 4

centripetal force: force pulling object towards center (keeping it in orbit)

Question 5

Centrifugal vs Centripetal

Answer 5

Centrifugal: pulls outward (centrifuge)
Centripetal: pulls inward, orbit.
