What type of energy is stored energy called?
Potential energy
This energy is present when an object is at rest and has the potential to move.
What type of energy is associated with motion?
Kinetic energy
This energy is present when an object is in motion.
Energy cannot be created or destroyed; it can only change from one form to another. This principle is known as the ________.
Conservation of energy
This principle highlights the transformation of energy types.
What is the term for the push or pull that causes an object to move?
Force
Force is necessary to change the motion of an object.
What type of energy makes things feel hot?
Thermal energy
This energy is related to the temperature of an object.
The measure of how hot or cold something is can be determined by ________.
Temperature
Temperature is measured using a thermometer.
The transfer of heat through touching is called ________.
Conduction
This process occurs when heat moves from a hot object to a cooler one through direct contact.
The warming of soup in a pan is an example of ________.
Convection
Convection involves the movement of heat through fluids (liquids and gases).
What is a good conductor of heat that can quickly get hot?
Metal
Metals are known for their ability to transfer heat efficiently.
What is an insulator?
A material that slows down heat transfer
An example is the cardboard sleeve around a cup, which prevents heat from reaching the hand.
Match the description: A stream running down a hill is best described as ________.
Kinetic energy
This describes energy in motion.
Match the description: A book on a desk is best described as ________.
Potential energy
This describes energy stored due to its position.
Match the description: Food before it is eaten is best described as ________.
Potential energy
This energy is stored in the food until consumed.
What is an example of kinetic energy?
A plane flying through the air
Kinetic energy is the energy of motion.
What is an example of food before it is eaten?
Potential energy
This illustrates the concept of potential energy in relation to food.
What are examples of conductors?
- COPPER
- SILVER
- GOLD
Conductors are materials that allow electricity to flow through them.
What are examples of insulators?
- PLASTIC
- RUBBER
- WOOD
- CARDBOARD
Insulators are materials that do not allow electricity to flow through them easily.
What type of materials keep water hot?
AN INSULATING MATERIAL LIKE FOAM, PLASTIC, OR RUBBER
Conductors can also be used, but insulators are more effective for retaining heat.
What is the difference between heat and thermal energy?
HEAT IS THE TRANSFER OF THERMAL ENERGY
Thermal energy is the random motion of particles in matter.
True or false: If a pond freezes, its thermal energy is being destroyed.
FALSE
Energy cannot be created or destroyed; it can only change forms.
Give an example of how thermal energy is transferred from one object to another.
A PAN BEING PLACED ON A HOT STOVE
This demonstrates conduction, where heat is transferred through direct contact.
