- A leaf gliding in the wind
- A bat striking a baseball
A bat striking a baseball

The Tesla lost energy.
This word describes the push or pull on an object that makes it move or stop?
Force
When you clap your hands together real fast, what kind of energy makes the CLAP sound?
Sound Energy
Elphaba sets her cruise control at 70 mph while Glinda sets hers at 60 mph. Which driver's car arrives first and uses the most energy?
Elphaba's car
A green stripped marble rolls into a stationary blue spotted marble, causing the blue marble to roll away. Did the green marble transfer ALL or MOST of its energy?
Most of its energy
When two toy cards collide head-on and bounce backward the same distance, what does this tell us about the force used to push them?
They were pushed with similar amounts of force and had similar energy.
What do we call it when two moving objects smash or bump into eachother?
When a glowing flashlight shines across a dark room, what form of energy lets you see where you are walking?
Light energy
Ball #6 arrives at the soccer goal before Ball #7. Which ball has slower speed and less energy?
Ball #7
Before a collision, a basketball is rolling while a soccer ball is sitting still. What happens to the soccer ball's energy AFTER the basketball hits it?
During a collision, not all energy goes into the moving objects, what THREE forms of energy is the extra energy converted to?
100 points per form of energy (partial points available!!)
Sound, Heat, and Light
The ability to do work or cause a change in speed and motion
Energy
If you rub your hands together fast, you start to form friction. What kind of energy did your motion turn into?
Heat energy
If a cheetah is running at top speed and trips over a GIANT banana peel, what happens to its energy of motion? Where and what type of energy would it energy transfer to?
Energy will be transferred into the ground and SPLAT, sound energy, and maybe a few cuts and bruises.
Double points if team said both, ground and sound energy.
If you high-five your partner really hard, what two forms of energy are being created besides motion?
Sound (CLAP) and Heat (ouch...my hands sting now!)
OMG! AN ALIEN SPACESHIP CRASHED INTO THE GIANT MARSHMALLOW MOON ON THE PLANET KRYPTONITE!! Why did it not make a loud metal CLANG sound?
Marshmallows are soft and absorb energy instead of making a loud metal sound!
Also, the moon is not made out of marshmallows and there is no planet named Kryptonite.
This measures how fast or slow an object is moving from one place to another.
Speed
When thunder cracks and lightning flashes during a big storm, what two forms of energy are being released at the same time?
Sound energy (thunder) and light energy (lightning)!
Double points if correct!
What travels faster? A rocket ship blasting into space, or a turtle riding a skateboard down a hill?
The rocket ship, unless the turtle has turbo boosters!
+100 points if team has creativity with answer.
Two giant bowling balls crash into each other. It is possible for them to collide without making any sound at all?
No! Energy will transform into sound energy during a crash!
If a superhero pushes a bus with maximum force and a toddler pushes a tricycle with tiny force, which vechile has more energy of motion?
The school bus!
What is it called when energy is passing on from one object to another object during a crash?
Energy Transfer
When you rub a match against a box and it catches fire, it creates a bright glow and burns your fingers. What two forms of energy did it make?
Light and heat!
