  1. Who Wants to be a Millionaire? Chapter 12 review

  2. $100 When an unbalanced force acts on an object, A the object’s motion does not change. B the object accelerates. C the weight of the object decreases. D the inertia of the object increases.

  3. $200 The unit of force is the: • Joule • Kilogram • Meter • Newton

  4. $300 Sliding friction: • acts in the direction of motion. • equals the weight of the box. • is usually greater than static friction. • acts in the direction opposite of motion.

  5. $500 Projectile motion is caused by A the downward force of gravity. B an initial forward velocity. C a final vertical velocity. D the downward force of gravity and an initial forward velocity.

  6. $1,000 What is conserved when two objects collide in a closed system? • Acceleration • Momentum • Speed • Velocity

  7. $2,000 The product of an object’s mass and velocity is its: • Centripetal force • Momentum • Net force • Weight

  8. $4,000 If a force of 10N is applied to an object with a mass of 1 kg, the object will accelerate at: • 0.1 m/s2 • 9 m/s2 • 10 m/s2 • 11 m/s2

  9. $8,000 Your weight = • Your mass • Your mass/the net force acting on you • ( Your mass) (acceleration due to gravity) • (Your mass) (your speed)

  10. $16,000 Which of the following is most effective over long distances? • Electrical • Gravitational • Magnetic • Strong nuclear

  11. $32,000 The forces acting on a falling leaf are: • Air resistance and fluid friction • Gravity and air resistance • Gravity and static friction • Weight and rolling friction

  12. $64,000 What is the momentum of a 50 kg ice skater going 2m/s? • 25kg/m/s • 48 kgm/s • 50 kg • 100 kgm/s

  13. $125,000 What force is responsible for the repulsion between two positively charged particles? • Centripetal • Electric • Gravitational • Nuclear

  14. $250,000 The centripetal force acting on a satellite in orbit: • Acts as an unbalanced force • Changes the direction of the satellite • Is a center directed force • All of the above

  15. $500,000 What is the acceleration of a 750 kg car having a crane exerting a force of 900N on it? • 670,000 kgm/s2 • 1.2 kgm/s2 • 0.83 m/s2 • 1.2 m/s2

  16. $1,000,000 The mass of a newborn baby is 4.2 kg. What is the baby’s weight? • 4.2 kg • 4.2 N • 41 N • 41 kg
