W=F×dW = F \times dW=F×d
Joules (J)
Movement in direction of applied force
P=WtP = \frac{W}{t}P=tW
P=F×vP = F \times vP=F×v
Watts (W)
I=mv−muI = mv - muI=mv−mu
Newton seconds (Ns)
KE=12mv2KE = \frac{1}{2}mv^2KE=21mv2
PE=mghPE = mghPE=mgh
Quadruples the kinetic energy
Energy cannot be created or destroyed
m1u1+m2u2=m1v1+m2v2m_1u_1 + m_2u_2 = m_1v_1 + m_2v_2m1u1+m2u2=m1v1+m2v2
Drag force balances driving force, acceleration is zero
D=kvnD = kv^nD=kvn
