Define momentum Give the equation for conservation of momentum State the law of conservation of momentum What is the momentum of the two cars after collision if its momentum before collision is 50 kgm/s? What is the unit for momentum? Calculate the momentum of a car, which has a mass of 1000 kg and moves with a velocity of 20 m/s. The total momentum of two objects after collision is 65.8 kg. m/s. What would be the total momentum before the collision happened? State the relationship of momentum to mass and velocity A large truck collides with a small car, which undergoes the greater change in velocity? In order to decrease the force of impact in a collision, you should: (relationship of Force and Time of impact) TRUE OR FALSE. (Explain) The less massive object will have less momentum if the velocities are the same Imagine, you are riding a bus going to Baguio then suddenly the bus driver increases the velocity. Explain what you feel as the velocity increases and the momentum of the bus. TRUE OR FALSE. (Explain) The greater the velocity the lesser the momentum of an object. TRUE OR FALSE. (Explain) When the mass and velocity of an object increases its momentum also increases. TRUE OR FALSE. (Explain) Two different objects are moving at the same speed. The larger object is more difficult to stop. TRUE OR FALSE. (Explain) Two objects collide. Object A has greater mass and velocity while Object B has smaller mass and velocity. In this case, Object A has greater change of momentum or impulse.

Two skaters stand facing each other. One skater’s mass is 60 kg and the other’s mass is 72 kg. If the skaters push away from each other without spinning. What happened to the momentum and the direction? A rubber ball and a lump of putty have equal mass. They are thrown with equal speed against a wall. The ball bounces back with nearly the same speed with which it hit. The putty sticks to the wall. Which objects experiences the greater momentum change? A freight car of mass 20,000 kg moves along a railroad track with a constant speed of 15 m/s. What is the momentum of the car? A 10 kg object moves at a constant velocity 2 m/s to the right and collides with a 4 kg object moving at a velocity 5 m/s to the left. Calculate the combined velocity of the objects. Let’s assume there’s a car speeding toward you, out of control without its brakes, at a speed of 27 m/s (60 mph). Can you stop it by standing in front of it and holding out your hand? Why not? Two trains, Big Red and Little Blue, have the same velocity. Big Red, however, has twice the mass of Little Blue. Compare their momentum.
