Matter and Energy
Transcript of Matter and Energy
There's chemical energy stored in food that your body uses to walk, run, and lift things.
Power plants, and batteries provide us with electrical energy.
The sun is our major source of light energy.
Wind, moving water, airplanes, and sound waves all have mechanical energy.
Vibrating atoms cause heat, and that makes thermal energy.
Nuclear energy is released from inside atoms, when they are broken apart, or together.
We heard that Miss Emmer had just finished the fitness testing for grades 4 through 6. Kinetic Energy: It's Everywhere Defintion of thermal expansion: Thermal expansion is the tendency of matter to change in volume in response to a change in temperature. - wikipedia At the concessions stands, water boils when they are making hot dogs, hamburgers.etc. So here is a picture of water boiling When water is heated, it expands. When water is heated, its density decreases, and its volume expands This is a picture of water boiling. Water boiling is an example of thermal expansion. This is a picture of water boiling. Water boiling is an example of thermal expansion. Transfer of energy by heat example: One example could be if the player hits the ball with something sharp, the ball could deflate. This has changed size, shape, and form.
Motion of atoms, state, and changeof state, other
physical changes, chemical changes, temperature
and change of temperature, transfer of energy by
heat, and thermal expansion. She's curious how the
terms listed above can be related to physical
education, and your daily life at home. So we decided
to find out how in this presentation kinetic energy:
it's everywhere. We created a visual presentation of
one large event, and other minor events that took
place in the large event.
Kitetic energy is really everywhere. It is the energy of motion so when there's motion, there's kinetic. One example is a basketball being dribbled. Temperature and change of temperature
When the players run around their body heat increases, because they get sweaty. Also their heart rate goes up, and starts beating rapidly. When they slow down, and sit on the bench, their heart rate, and body heat decreases because they aren't moving. This is a change of temperature.

By: Ryan and Theo Energy can be transferred from on location to another, and one object to another. Energy can be transferred from one object to another by doing work. When work is done on an object, it results in a change in the objects motion, or a change in the onjects kinetics energy. Energy can be transferred from on location to another, as in the sun's energy travels through space to earth. THe two ways that energy can be transferred are by doing work, and heat transfer. An example at a game is when a hot dog is warmed up in the concessions stands. Also a common example is a fan changing electric energy to unwanted heat.
