Energy Basics
What do we call the ability to make things move or change?
Energy
What does “motion” mean?
movement
What is it called when two objects hit each other?
Collision
When you kick a ball, what are you transferring?
Energy
A circuit is a path for what to travel through?
electricity
Name one thing you do every day that uses energy.
walking / eating / playing / talking / turning on lights
If something moves faster, does it have more or less energy
More
In a collision, what happens to the energy?
it transfers (moves) from one object to another
When you rub your hands, and they get warm, energy changed into what?
Heat
What do we call a circuit that lets electricity flow?
closed circuit
What kind of energy makes light bulbs shine and TVs turn on?
electrical energy
Which has greater speed — a person walking or a car driving?
Which would cause a stronger collision: two rolling marbles or two bowling balls?
two bowling balls
When you bowl, how does the ball get its energy?
from your arm/hands pushing or throwing it
What happens when a circuit is open or broken?
The electricity stops flowing
Energy can change from one form to another. What type of energy do you get from the Sun?
What is light or heat energy?
You push two toy cars — one lightly and one hard. Which moves faster and why?
the one pushed harder because it got more energy
After two cars crash, where does the energy go?
Into sound, motion, and damage (it spreads out)
When a domino falls and hits the next, what happens to the energy?
it passes (transfers) along to the next domino
What part of a circuit gives energy to the electrons?
the battery
True or False — Energy can disappear completely when used.
False - Energy cannot be created or destroyed
A rock falls off a hill and speeds up as it drops. What kind of energy is increasing?
Kinetic Energy
If one object stops after a collision and the other keeps moving, what happened to the first object’s energy?
It is transferred to the second object
A moving swing slows down over time. Where did the swing’s energy go?
it changed into heat and sound
A student connects wires, a battery, and a bulb. The bulb doesn’t light up. Give one reason why.
a loose wire, open circuit, or dead battery
