- 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
