Speed and Energy
What happens to energy when an object moves faster?
It has more energy
What is a collision?
When two objects hit each other.
In science, what is a cause?
Something that makes something happen.
What is stored energy?
Energy saved for later use.
What is an energy transformation?
Energy changing from one form to another.
A slow bike vs. a fast bike—which has more energy?
fast bike
What happens when objects collide at faster speeds?
They cause more damage/change.
In science, what is an effect?
What happens because of the cause.
Name something that has stored energy.
Battery, food, stretched rubber band
A battery powering a flashlight changes energy into what?
Light energy.
What is the cause in this situation: “A ball moves faster and has more energy”?
the ball moving faster
Which causes a bigger dent: slow crash or fast crash?
fast crash
Identify the effect: “The car sped up and caused a bigger crash.”
A bigger crash
What happens to stored energy when used?
It changes into another form.
Food gives your body energy to do what?
Move
What is the effect when speed increases?
the energy increases
What changes during a strong collision?
shape of objects
Identify the cause: “The clay ball flattened because it hit the table fast.”
it hit the table fast
A stretched rubber band has what kind of energy?
stored energy
What type of energy is used when you turn on a lamp?
Electrical → light energy.
Give an example of something with high speed and high energy.
race car, cheetah, fast baseball
Why do scientists test collisions?
To see how speed affects damage/shape change.
Complete this: Faster speed → ______ energy → ______ damage
more energy, more damage
What is released when stored energy is used?
Movement, heat, or light
Give an example of stored energy turning into motion.
Rubber band snapping, roller coaster going down
