Understanding Newton’s Laws of Motion and Momentum

Explore the three fundamental laws of motion developed by Sir Isaac Newton, which describe the relationship between an object and the forces acting on it. Learn about inertia, acceleration, and action-reaction forces, as well as the concept of momentum and its importance in understanding the motion of objects. Additionally, delve into projectile motion, examining how objects move through the air under the influence of gravity. This comprehensive overview will deepen your understanding of motion in our physical world.

  2. The resistance and object has to a change in motion.

  3. What is Inertia?

  4. In the absence of this force, a ball rolling on the ground will continue in a straight line forever.

  5. What is friction?

  6. An object will stay at rest unless acted upon by this.

  7. What is an unbalanced force?

  8. You throw a coin upward while sitting in the front seat of a decelerating car. This is were the coin will land.

  9. What is the dashboard?

  10. This Italian scientist (1564-1642) studied how gravity effects objects with constant acceleration.

  11. Who is Galileo Galilei?

  12. This causes an objects velocity to change.

  13. What are unbalanced forces?

  14. The acceleration of an object is equal to the net force applied divided by this quantity.

  15. What is mass?

  16. The acceleration of a car with a mass of 1,000 kg being moved by a force of 4,000 Newtons.

  17. What is 4 m/s/s ?

  18. A measure of the force of gravity acting on an object.

  19. What is weight?

  20. Find the gravity on Mars if an 88Kg astronaut on earth weighs 863 Newtons, but only 325.6 Newtons on Mars.

  21. What is 3.7 m/s/s ?

  22. When one object exerts a force on a second object, the second object exerts what back?

  23. What is an equal and opposite force?

  24. When rowing a boat in the water, this provides a forward force on the boat.

  25. What is the water?

  26. What seatbelts provide a to keep car passengers from flying forward during a sudden deceleration.

  27. What is provide a reaction force?

  28. This device uses the third law of motion. In it expanding gases provide and action force to propel the object forward.

  29. What is a rocket?

  30. In this important science book, Sir Isaac Newton defined the laws of motion.

  31. What is Principia Mathematica?

  32. The momentum for any object at rest.

  33. What is zero?

  34. The fact that if no net force acts on a system, the total amount of momentum remains constant.

  35. What is the law of conservation of momentum?

  36. A bowling ball rolls down an alley with 3,000 Kg*m/sec of momentum. After it strikes the pins, what is the total momentum of the pins and the ball?

  37. What is 3,000 Kg*m/sec?

  38. A 4 Kg bowling ball is rolling towards an identical stationary ball at 6 m/sec. After the collision, the first ball slows to 2 m/sec. Find the speed of the other bowling ball after the collision.

  39. What is 4 m/sec?

  40. A train car moving 20 m/sec collides and attaches to an identical stationary car. The original momentum of the moving car was 45,000 Kg*m/sec. Find the speed of the cars together.

  41. What is 10 m/sec?

  42. Horizontal and vertical.

  43. What are the types of motion found in a projectile?

  44. In the absence of this force, a projectile will have constant horizontal velocity.

  45. What is air resistance?

  46. A toy rocket is launched vertically into the air at 60 m/sec. If it lands at the same height, find the speed of the rocket at its peak.

  47. What is 0 m/sec?

  48. A penny and a silver dollar are knocked off a table by different forces, find the order that they will land on the floor.

  49. What is they both tie?

  50. This is reached when the force of gravity equals the drag force on a falling object.

  51. What is terminal velocity?
