Energy and James Watt

1. What was James Watt's contribution to the Industrial Revolution?
   • Manufacture of Scottish instruments
   • Linked heat to mechanical work
   • Invention of the steam engine
   • Thermal machine studies
2. What was James Watt's goal to open a shop in Glasgow?
   • Sell steam engines
   • Made mathematical instruments
   • Test your experiments and sell them
   • Sell books from your studies
3. What was James Watt's patent after running a small test engine?
   • To reduce the consumption of steam and fuel in fire engines
   • Best engine manufacturer
   • Use on airplanes
   • More sophisticated engines
4. A steam engine developed by James Watt (1736-1819) is not revolutionary as the world of energy production, but rather the development of iron and steam villages. It is necessary to develop the technology mentioned in the text.
   • Streamlined communication and transport networks, contributing to other industrial sectors.
   • Led to the reduction of the scale of production in industries and reduced working hours.
   • Expanded scientific knowledge, but brought economic losses to England.
   • Was restricted to the areas of the factories, having little influence in the daily life of the populations.
5. What is the energy of Newton's pendulum experiment? | - gravitational potential || elastic potential ||| kinetic
   • |, ||, and |||
   • Only |
   • Only |||
   • | and |||
6. In the Newton pendulum experiment, thanks to which action does the ball fall and in what energy does it transform?
   • Weight and gravitational potential energy
   • Gravity and kinetic energy
   • Weight and kinetic energy
   • Gravity and gravitational potential energy
7. In Newton's pendulum, what happens when the ball that is released hits the nearest ball?
   • Lift the nearest ball
   • Raises the ball from the other end at a greater height
   • Transfer energy by causing the ball of the other end to rise at the same height
   • Raise the two balls
8. What is the definition of kinetic energy and gravitational potential respectively?
   • Gravitational attraction of the earth / elastic properties of a spring
   • Elastic properties of a spring / relation of the movement of bodies
   • Relation of the movement of bodies / gravitational attraction of the earth
   • Relation of the movement of bodies / elastic properties of a spring
9. A 3 kg lead ball is launched from the ground vertically upwards with speed of 40m / s. What is the value of Kinetic Energy at the time of launch?   (EC = 0,5 x mv²)
   • 240 J
   • 120 J
   • 4.800 J
   • 2.400 J
