  1. MOMENTUM (p) is defined as the product of the mass and velocity-is based on Newton’s 2nd Law F = ma F = mΔv t Ft=mΔv IMPULSE MOMENTUM

  2. CHARACTERISTICS OF A MOVING OBJECT A moving object has both kinetic energy and momentum. KE = ½ mass x velocity2 P = mass x velocity

  3. Ex. Compare the KE and momentum of two objects with the following characteristics: m1 = 60 kg v1 = 4 m/s m2 = 6 kg v2 = 40 m/s Solving for momentum, p: P1 = m1 v1 = (60 kg) (4 m/s) = 240 kg-m/s P2 = m2v2 = (6 kg) (40 m/s) = 240 kg-m/s Solving for KE: KE1 = ½ m1 v12 = ½ (60 kg) (4 m/s)2 = 480 J KE2 = ½ m2v22 = ½ (6 kg) (40 m/s)2 = 4800 J Therefore object 2 has the same momentum but 10 times the KE of object 1

  4. Both KE and momentum are conserved in an elastic collision.
