Which of the following graphs best represents the relationship between the gravitational potential energy of a freely falling object and the object's height above the ground?
The picture shows a flashlight that is turned on. The flashlight is producing light. What other type of energy is being produced?
electrical energy, as it is carried by the rays of light
mechanical energy, as electricity moves through the flashlight
sound energy, as light makes sounds as it bounces off objects
heat energy, as the flashlight will get warmer the longer it is left on
The diagram below illustrates four phases of a model rocket's flight. Use the diagram to answer any questions that follow. When is the rocket's potential energy at its maximum and kinetic energy its minimum?
when the rocket's at the peak of flight and when the rocket is free falling
when the rocket is at the peak of flight, only
when the rocket's motor is burning and when the rocket is ascending
when the rocket is free falling, only
he picture below shows a toy car in the process of rolling down a ramp. At point X, the kinetic energy is 50 Joules (J), and the potential energy is 30 J. What is the total energy in the system once the car reaches the bottom of the ramp?
80 J, because the energy in the system can change form but cannot be created or destroyed
20 J, because the energy in the system cannot change form but can be created and destroyed
30 J, because the potential energy is the only energy at the bottom of the ramp
50 J, because the kinetic energy is the only energy at the bottom of the ramp

Inside a room, the air is often warmer near the ceiling than near the floor. Which of the following accounts for this difference in temperature?
radiation
insulation
conduction
convection
Which type of heat transfer is BEST occuring between the fire and the cat
Conduction because the cat is directly touching the fire to stay warm
Convection because the hot air around the fire is rising to keep the cat warm
Radiation because the electromagnetic waves of the fire make the cat feel warm

conductor
metal
radiator
insulator
