Energy, Speed, and Moving Objects
What are some forms of energy you can easily observe? (name at least two)
What is it called when one object bumps into another object?
A collision
What is the energy from the sun called?
electromagnetic energy
This is a property that causes matter to have force, electrical force
What is Electrical charge
This is a term that means "to produce"
What is generate?
Energy at rest is what kind of energy?
Potential Energy
When energy moves from one object to another, what is that called?
energy transfer
Heat energy is also called what type of energy?
Thermal energy
The flow of charged particles in the same direction is called what?
Electric current
This is a form of energy we can see.
Light Energy
Energy in motion is what kind of energy?
Kinetic Energy
When energy changes form from one form to another, what is that called?
Energy Transformation
Sound energy travels in this form.
What are vibrations and waves?
Name 3 materials that are insulators
rubber, wood, glass, paper
What is the source in an electric current?
The starting point of energy (sometimes a battery)
When dominos fall, what happens to the energy?
Some of it is transferred to the next domino and some is transformed into sound energy.
What happens to energy in a collision?
Energy changes - it is transferred or transformed.
What happens to particles of matter as they are heated up?
Name 3 materials that are conductors
silver, gold, steel, copper, salt water
Something that does not allow energy to flow through it is called what?
An insulator
How does energy affect particles of matter?
Energy can make the particles move close together or far apart.
When two objects collide, what factors affect how much energy is transferred or transformed? (There are 3 - Think about our experiment with different sized balls colliding with the cup)
speed, mass, size
What happens to particles of matter that are cold?
They slow down and move more closely together
What causes a light bulb to glow in an electric circuit?
Electrical energy is transformed or changed to light energy
Something that allows electricity to flow through it is called what?
A conductor
When you watch a roller coaster going down the track, you are observing what kind of energy?
kinetic energy or energy in motion
What happens to the energy in a baseball bat when it hits a baseball?
Some of the energy is transferred to the ball and makes it move. Some of the energy is transformed into sound energy and we hear a "crack!" as the ball and bat collide
When you have a cup of hot chocolate? What happens to the heat energy in the cup as you hold it?
The heat energy is transferred from the inside of the cup to the outside of the cup and the hot chocolate becomes colder.
The battery provides energy that causes an electric current to flow. The wire provides a path for the current.
This is a device which controls the flow of electricity
What is a resistor?
