KE PE Resources Work

Row 1, Col 1 The kinetic energy of an object can be found if you know these two things. What are speed and mass?

1,2 When you stretch a rubber band you give it this. What is potential energy?

1,3 Geothermal energy is this type of resource. What is renewable?

1,4 Force x distance What is the formula for work?

2,1 Kinetic energy is defined as this. What is the energy of motion?

2,2 Batteries using chemicals to produce elctricity. What is an energy transformation?

2,3 Coal, petroleum and natural gas. What are fossil fuels?

2,4 True or False Sound energy can travel through a vacuum. What is false?

3,1 The sum of an object’s potential and kinetic energies. What is mechanical energy?

3,2 When you are jumping on a trampoline, your energy at the top of your jump. What is maximum PE?

3,3 The energy conversion used by plants during photosynthesis. What is light energy to chemical energy?

3,4 Energy from the sun is captured, then stored in plant and animal remains converted over millions of years is how this is made. What is how fossil fuels are formed?

4,1 This type of energy changes with the kinetic energy of its particles. What is thermal energy?

4,2 This variable can affect the potential energy of an object. What is height or mass?

4,3 Define and describe an energy transformation. What is the change from one form of energy to another and for example the chemical energy in gas is changed to kinetic/mechanical energy?

4,4 Work is measured in these units also known as a Newton meter. What are joules?

5,1 The energy of a skier at the bottom of the hill at the instant before he stops. What is a the maximum kinetic energy?

5,2 Weight x height (mass x gravity) What is the formula for gravitational potential energy?

5,3 The forms of renewable energy. What are solar, wind, geothermal, biomass and hydro (water)?

5,4 You lift a box of xmas ornaments from the floor to the table. Over the course of the year, you grow 2 inches. You go back the next year and lift the same box, how has the work you have done been affected? What is the work is the same?
