What is a person running? Any object in motion has kinetic energy.
What is a main idea?
This is the author's message about a topic?
Joe_________ the key from one drawer to another.
Which vocabulary word do we use?
Exert, Transfer, Interact, Force, Convert
What is Transfer?
Transfer means to move an object from one place to another place.
In Paragraph 1, what textual evidence can you find about forces exerted on people? You have 30 seconds to state the evidence.
Through these forces, energy can be transferred from one person or object to another.
The text contrasts potential and kinetic energy. How does potential energy differ from kinetic energy?
Potential energy is stored in an object based on its position while kinetic energy is the energy an object has due to its motion.
A main idea can be expressed by being implied or directly expressed in a story.
Implied means: if something is implied, it is understood to be true or to exist, although it is not stated directly
It is important to know how those two medicines _______ with each other.
Which vocabulary word do we use?
Exert, Transfer, Interact, Force, Convert
What is Interact?
Interact is act in such a way as to have an effect on another object or person.
In Paragraph 2, what textual evidence can you find about forces exerted on people? You have 30 seconds to state the evidence.
The pitcher pulls their arm back, then swings it forward to roll the ball to the kicker.
What is a force?
a push or pull in a specific direction
What is one of the main ideas of the text: Let's Play some Kickball?
In a kickball game, different forces help energy transform and transfer from one person or object to another.
The _________ of the wind knocked down the trees.
Which vocabulary word do we use?
Exert, Transfer, Interact, Force, Convert
What is a force?
A force is a push or a pull on an object.
In Paragraph 4, what textual evidence can you find about forces exerted on the ball? You have 30 seconds to state the evidence.
But since some of the energy has been converted into heat and sound, the ball moves a little slower, and doesn’t go as high.
The star kicker transferred energy from her foot to the ball as she kicked it into the air. What happened to that energy?
The energy stayed in the ball and changed between kinetic and potential energy, then left the ball as heat, sound, and kinetic energy in another player’s body.
What is the second main idea: Let's Play some Kickball?
Forces are either kinetic or potential depending upon the situation of the forces involved at that time.
He hurt his back because he_________ himself too much.
Which vocabulary word do we use?
Exert, Transfer, Interact, Force, Convert
What is exert?
Exert is to to put (oneself) into strenuous, vigorous action or effort
In Paragraph 3, what textual evidence can you find about forces exerted on people? You have 30 seconds to state the evidence.
For just a moment, it’s completely still, up in the air. At this point, the downward force of earth’s gravitational pull has equaled the upward force of the star kicker’s kick.
Read the following sentences from the text.
“As the ball soars up into the sky, it begins to slow down. The force of gravity is pulling down on the ball, even though the force of the star kicker’s foot sent the ball sky high. As the ball soars through the air, its kinetic energy turns into gravitational potential energy; it slows down as it gets higher. When the ball reaches its highest point, it has its greatest amount of potential energy, and no kinetic energy at all. For just a moment, it’s completely still, up in the air. At this point, the downward force of earth’s gravitational pull has equaled the upward force of the star kicker’s kick. Then, once the ball begins to arc downwards, the potential energy changes back into kinetic energy. ”
The ball has more kinetic energy when it is closer to the ground.
As pitchers lift the ball, they transfer energy from their muscles to the ball. Is the energy that is being converted created or destroyed? Explain
Law of Conversation of Energy: Energy can be transferred from one object to another, but it cannot be created nor destroyed.
He _________ the sofa into a bed.
Which vocabulary word do we use?
Exert, Transfer, Interact, Force, Convert
What is convert?
Convert is to cause to change in form, character, or function.
In Paragraph 5, what textual evidence can you find about forces changing into other energy such as sound? You have 30 seconds to state the evidence.
That is why there is a loud smacking sound when the ball meets a player’s hands!
