4. Phys.B: Giancoli Ch.3: Projectile and Circular motion
F = ma in 2D: F = Fx i + Fy j where Fx = m ax and Fy = m ay.
Uniform circular motion:
a = v2/r
Team 1: #24
Team 2: #56
Team 3: #62

5. Phys.B: Giancoli Ch.4: Newton’s Laws
N1: Every body continues in its state of rest or of uniform speed in a straight line as long as no force acts on it.
N2: F=ma (Ex. 4-15)
N3: Whenever one force exerts a force on a second object, the second exerts an equal and opposite force on the first.
Each team choose one:
#5, 21, 34, 40, 55, 72

6. Phys.B: Giancoli Ch.6: Gravity
F = GmM/r2
Force on m is F = ma a = v2/r
Solve for period T v=2pr/T
