1average velocityvₐᵥ = d/t
2displacementd = ∆x = net distance + direction
3average accelerationa = ∆v / ∆t
4air resistanceThe acceleration will decrease because the force is decreasing due to increasing resistance or friction at higher speeds.
5terminal velocityweight = friction
net force = 0
acceleration = 0
speed = constant
6Projectile motion: horizontal componentsv₀ₓ = v₀ cos θ₀
vₓ= v₀ₓ
x = v₀ₓt
aₓ = 0
7projectile motion: vertical componentsv₀ᵧ = v₀ sin θ₀
vᵧ= v₀ᵧ - gt
y = v₀ᵧt - ½ gt²
aᵧ = -g
8centripetal acceleration (magnitude)a(c) = v² / r
9Satellites orbiting the Earth- They are in free fall.
- Their centripetal acceleration due to the Earth's gravity.
- They are accelerating toward the Earth.
- They never crash into the Earth's surface because the Earth is round (the surface curves away from the satellite at the same rate as the satellite falls).
10Object tossed straight upwardv₀ = -v₁
t(up) = t(down)
11kinematics formula: no v₀d = vt - ½at²
12kinematics formula: no ad = vₐᵥ t = (v₀+v)t / 2
13kinematics formula: no tv² = v₀² + 2 ad
14kinematics formula: no vd = v₀t + ½at²
15kinematics formula: no dv = v₀ + at
