Momentum Momentum can be defined as “inertia in motion." It is moving mass All objects have mass; so if an object is moving, then it has momentum Momentum depends on two things: mass and velocity
Momentum Momentum = mass X velocity p = mv where p = momentum, m = mass and v=velocity Unit for Momentum: Kgm/s
Which has more momentum and why? A 1400 kg truck traveling at 50 m/s Or a 500 kg car traveling at 50 m/s
Which has more momentum and why? A 1400 kg truck traveling at 10 m/s Or a 500 kg car traveling at 50 m/s
Which has more momentum and why? A 1400 kg truck traveling at 0 m/s Or a 500 kg car traveling at 0 m/s
White board practice 1. Calculate the momentum of a 0.15 kg ball that is moving toward home plate at a velocity of 40m/s.
White board practice 3. A track athlete throws a 2kg discus into a field with a velocity of 21m/s. What is the momentum of the discus?
White board practice 4. Calculate the momentum of a 700g ball that is going 0 m/s.
