Two model trains are running on tracks that are lined up next to each other. The two trains are not moving at the same speed. What would cause one train to move faster than the other?
The slower train’s cars have less mass
The faster train has more energy
The faster train has a wider track
The slower train has an older engine
Which animal shown on the chart uses the least amount of energy while running?
Cheetah
Rabbit
Elephant
Chicken
Mrs. Stone’s class did an experiment to determine from what height on a ramp a toy carhad the most energy. The results are shown in the table below. From which interval did the car have the most energy and why?
The car had the most energy at 5 cm. because it went the least distance and had less
speed.
The car had the most energy at 15 cm. because it went the greatest distance so it had
the greatest speed.
The car had the most energy at 20 cm. because it went the greatest distance so it had
the greatest speed.
The car had the same amount of energy at all intervals because the mass of the car was
the same.
Plants make their own food through photosynthesis using energy from the sun.
What type of energy transformation is occurring in the plant?
light energy is becoming mechanical energy
thermal energy is becoming chemical energy
thermal energy is becoming electrical energy
light energy is becoming chemical energy
Angela has a Slinky toy made out of a coil of wire. She places the toy at the top of some
stairs. The toy can travel down each step, end-over-end. Which type of energy does the
toy have when it is placed at the top of the stairs?
Electrical Energy
Kinetic Energy
Magnetic Energy
Potential Energy
A sewing machine uses a battery to make a needle move. The needle goes up
and down quickly. Which energy transformation is taking place?
electrical to chemical
chemical to mechanical
mechanical to electrical
electrical to sound
This picture shows parts of a flashlight. Which part of the flashlight stores energy to light the bulb?
case
mirror

The ram on a crane uses the force of kinetic energy to push a spike into the ground.
From which position should the ram be released to have the greatest kinetic energy
when it hits the spike?
1

The coil glows when electrical energy is used.
Besides light, what other kind of energy is emitted
when the coil is glowing?
Mechanical Energy
Chemical Energy
Sound Energy
Thermal Energy
A doorbell circuit converts electrical energy into mechanical energy. The mechanical energy is in the form of vibrations that ultimately produce what kind of energy?
Chemical Energy
Thermal Energy
Sound Energy
Light Energy
Barbara placed a marble at different places on a ramp. At which place will the marble have the most potential energy?
What is potential energy?
The energy an object has due to its motion.
The energy an object has due to its position.

The energy that increases the temperature of an object.
What is an example of kinetic energy?
a book sitting on a shelf
a ball rolling down a hill
a runner about to start a race
a window getting hot from the sun
Which picture represents an object that can convert light to electrical energy?
An illustration of a roller coaster is shown.
At which point in the roller coaster’s journey along the track does it have the greatest
potential energy?
W
X
Y
Z
The amount of kinetic energy an object has depends on which of the following?
mass and volume
volume and speed
mass and speed
speed and position
The pictures below show what happened to a flashlight that was left turned on in a dark
room. Which reason best explains why the flashlight stopped shining?
The light spread out in all directions.
The lens of the flashlight blocked
the light.
The wall in the dark room absorbed
all the light.
The batteries of the flashlight used
all the available stored energy.
Students built an electric circuit in class.
What is the order of the energy transformation
that occurs when the circuit is closed or on?
