N·s (or kg·m/s)
The vector quantity defined as the integral of a force over the time interval during which it acts, equal to the net change in momentum.
J = ∫ F dt = Δp = m vf - m vi
Inclined Plane
Classical Mechanics
Dimensionless
A simple machine consisting of a flat supporting surface tilted at an angle to the horizontal.
MA = L / h = 1 / sin θ
Inelastic Collision
Classical Mechanics
kg·m/s, J
A collision in which total linear momentum is conserved, but total kinetic energy is not conserved.
∑ p_i = ∑ p_f, KE_final < KE_initial
Inertia
Classical Mechanics
kg
The natural resistance of any physical object to any change in its velocity or state of motion.
