Energy, Force and Motion
Energy exists in many forms and moves from one form to another. Forces cause
motion to occur.
Unit Essential Question
How does energy, force and motion play a part in your life?
LEQ 1: What is movement (motion)?
Concept: Interaction of forces and motion
How do things move? Above Below Ahead Behind Up Down Horizontally Vertically Right Left
Concept: Interaction of forces and motion
How do we know something has moved?
By looking at the things that are not moving around it.
FRAME OF REFERENCE
Concept: Interaction of forces and motion
You can tell that an object has moved when its __________ has changed.
position
Concept: Interaction of forces and motion
Now answer the question:
What is movement (motion)?
Concept: Interaction of forces and motion
LEQ 2: What makes objects move, stop or change direction?
Concept: Interaction of forces and motion
Concept: Interaction of forces and motion
Force
WHAT IS FORCE?
Any push or pull that causes an object to move, stop or change speed or direction.
Concept: Interaction of forces and motion
Force The greater the force, the greater the change
in motion.
The bigger an object is, the less effect a force will have on it. The smaller
an object is, the
more effect a force
will have on it.
Concept: Interaction of forces and motion
Inertia
Inertia keeps an object still or keeps it moving.
A moving object will keep moving until something stops it.
An object that is not moving will not move until something moves it.
Concept: Interaction of forces and motion
When an object is in motion it tends to stay ...
Concept: Interaction of forces and motion
When an object is still it tends to remain ...
Concept: Interaction of forces and motion
This is called…
Concept: Interaction of forces and motion
What is an example of a force between surfaces that slows or stops objects?
Concept: Interaction of forces and motion
Friction creates ______.heat
Concept: Interaction of forces and motion
Friction is the resistance to motion made by two objects rub each other.
Rub your hands together! What happens? The heat you feel is friction. Try faster and slow. What happens?
When you pull the brakes on your bicycle. The brake pressing against the tire and the tire rubbing against the street is friction.
Think of bowling. As the ball goes down the lane what happens? The ball begins to slow, this is friction. The ball may lean or start
rolling one direction or the other, this is friction.
Concept: Interaction of forces and motion
Gravity
The force that makes things fall to the ground on Earth is called gravity.
Gravity also holds Earth and the other planets in their orbits around the Sun.
The force of gravity also exists on the moon but it is not as strong as it is on the Earth. This is because the moon is much smaller than the Earth.
Concept: Interaction of forces and motion
Now answer the question.
What makes objects change speed or direction?
Concept: Interaction of forces and motion
LEQ 3: What connections can we make between force and motion?
Concept: Interaction of forces and motion
Do your Work!!!
WHAT IS WORK?
Work is done when a force is used to move an object a certain distance.
Concept: Interaction of forces and motion
LEQ 4:What are the different types of energy?
Concept: Types of Energy
Energy
Energy is the ability to do work.
Concept: Types of Energy
Energy
Two types of energy:
Kinetic (motion)
Potential (right now,it’s not moving, but it has the ability to move)Energy game
Concept: Types of Energy
Energy
Kinetic-moving energy (energy of motion)
Concept: Types of Energy
The energy of motion is __________ energy.
kinetic
Concept: Types of Energy
Potential Energy
Potential- stored energy (energy waiting to be used)
Concept: Types of Energy
The energy of position is _____________ energy.
potential
Concept: Types of Energy
Kinetic Potential
Concept: Types of Energy
Name the type of energy in each of the following
statements.
Concept: Types of Energy
The ball is rolling down the hill.
Concept: Types of Energy
The roller coaster is sitting at the top of the track.
Concept: Types of Energy
The pencil fell off the edge of the desk.
Concept: Types of Energy
The skier is at the top of the ski jump.
Concept: Types of Energy
Play the game!!!!
POTENTIAL KINETICENERGY
Concept: Types of Energy
Now answer the question:
What are the different forms of energy?
Concept: Types of Energy
LEQ 5: What are the different forms of energy?
Concept: Forms of Energy
Forms of Energy - Chemical
Ex: stored energy in food and fuel.
Concept: Forms of Energy
Forms of Energy - Electrical
Ex: batteries, electric in homes
Concept: Forms of Energy
Forms of Energy - Light
Ex: sun and lasers
Concept: Forms of Energy
Forms of Energy – Mechanical
Ex: wind, water falling over a water fall, sound
Concept: Forms of Energy
Forms of Energy - Nuclear
Ex: Sun, nuclear fusion
Concept: Forms of Energy
Forms of Energy - Sound
Ex: music, your voice
Concept: Forms of Energy
Forms of Energy - Thermal
Ex: stove, heaters, matches
Concept: Forms of Energy
Watch the Brainpop movie about energy
Now answer the question:
What are the different forms of energy?
Concept: Forms of Energy
LEQ 6: How does energy change form?
Concept: Conversion of Energy
Forms of Energy
CAN ENERGY CHANGE FORM? YES!
Ex: The fuel in a rocket changes from chemical energy to mechanical energy when the fuel burns
Concept: Conversion of Energy
Choose a picture and explain how the energy changes form.
Can you answer the Unit Essential Question???
How does energy, force and motion play a part in your life?
Think about what you do? Where does the energy come from? What is your body doing? What is moving around you?
