Answers 2024

1st Law of motion - correct answers ✅law of inertia (from galileo)

  • If an object is not moving, it will continue to not move
  • If an object is moving, it will continue to move 2nd Law of Motion - correct answers ✅acceleration ( net force/ mass) or Time rate change in velocity Speeding up as well as slowing down 3rd Law of Motion - correct answers ✅Law of force pairs (law of action and reaction) All forces come in pairs Recoil of gun Rocket engine Magnus effect - correct answers ✅How curve balls curve Law of Universal Gravitation - correct answers ✅All objects are attracted to any other object. This attractive force is gravity. The strength of Gravity Attraction depends on the masses of the two objects involved, and also the distance between the centers of the objects T/F - correct answers ✅T Weight is? - correct answers ✅The force of gravity on an object

Answers 2024

Less massive objects react how? - correct answers ✅quickly- they speed up quckly and slow down quickly Think about two bricks, to accelerate like 1 brick, you have to push them with twice the force T/F - correct answers ✅True, to push two bricks the speed of 1 you need twice the force Law of inertia example - correct answers ✅1.Stomping boots with mud/snow stuck to them.

  1. Biking, front wheel stops suddenly.
  2. Seatbelt Bowling ball and soccer ball pushed with the same force, which one is faster? - correct answers ✅Same, look at mass not weight Between a soccer ball and a bowling ball which one will stop first if starting at the same speed, the bowling ball or soccer ball? - correct answers ✅Bowling ball, because it has more mass. More mass = more inertia More inertia = more moving, keeps going and going What is the unit of mass? - correct answers ✅Kilograms What is the unit of force? - correct answers ✅Newton

Answers 2024

Force of Gravity - correct answers ✅Gravity (mass 1 x mass 2) / distance^ Law of universal Gravitation - correct answers ✅Gravity is an interaction between any two objects with mass Forces come in pairs T/F? - correct answers ✅True 8 types of energy - correct answers ✅1. Kinetic

  1. Gravitational
  2. Elastic
  3. Thermal
  4. Electromagnetic
  5. Radiant
  6. Chemical
  7. Nuclear Kinetic energy is - correct answers ✅energy of motion Gravitational energy is - correct answers ✅energy due to gravity Unit of Energy - correct answers ✅Joule Energy Transformation examples - correct answers ✅Joule's experiment

Answers 2024

  1. The furnace of a coal fired steam electric power plant is where coal is burned. What energy conversion takes place in the furnace? - correct answers ✅Chemical --> Thermal Which of the following energy transformations represents the operation of a wind turbine? - correct answers ✅Kinetic --> Electric Which of the following would increase the gravitational force between two objects? - correct answers ✅Moving the objects closer together How much energy does a 1200 W hair drier use if it runs for 10 minutes (600 seconds)? - correct answers ✅720000 J What is the gravitational energy of a 40 N bowling ball sitting on a shelf 1.5 m above the floor? - correct answers ✅60 J A toy car is moving. The net force on the car is in the opposite direction of motion. What will the car do? - correct answers ✅slow down An engine consumes 400 J of thermal energy while exhausting 300 J has an efficiency of? - correct answers ✅25%

Answers 2024

What is the natural, unforced motion of a moving object in space (like the moon or a planet). That is, what would the moition of the object be if there were no forces on it? - correct answers ✅It would move in a straight line Which of the following is not a fossil fuel? - correct answers ✅Hydrogen Gas What is the energy transformation that took place during Joule's experiment with the water wheel? - correct answers ✅Gravitational --> kinetic --> Thermal What is the metric unit of power? - correct answers ✅Watt What is the kinetic energy of a 18 kg bulldog running at 2 m/s? - correct answers ✅36 J = 1/2 x 18 kg x 2 m/s squared Chemical energy is transformed into gravitational energy when? - correct answers ✅a person walk uphill Under what condition can a force act on an object and yet do not work on that object? - correct answers ✅If the object doesnt move Current Gasoline powered automobiles have an overall efficiency of about 13 %.
