7 types of energy and define each
What is speed? How is it measured? (Formula) force is responsible for increasing the speed downhill
Why do you think the speed of the ball depends upon its release height? (Discuss both mass and height)
How does collecting multiple measurements during an investigation lead to a more reliable result?
difference between transformation and transfer of energy Give example of eachenergy relate to mass and height?
Explain using your lab a reference What is heat?
How is it measured? What happens to a car’s energy when it
impacts another car? (u can draw and explain a chain) What affect does the speed of the car have on the severity of
the collision? Why Where does the energy go after the collision? What are the differences between the energy of
motion (kinetic energy), stored energy (potential energy) and how does energy transformation connect these two
energy forms? How is energy transfer different from energy transformation, and give examples
Difference between the kinetic energy of an object and the random kinetic energy of the particles
that make up the object (heat energy)? What forms of energy are present in a swinging
pendulum, and where does the energy form the pendulum go? When you drop a ball onto a level
surface, it makes a few bounces and then comes to rest. Where did the energy of the ball go?
What energy transformations take place?
What energy transfers take place?
Where has the original potential energy of the golf ball gone when the ball comes to rest?
Draw the following energy chains. ----Include transformation and transfer of energy!! (Explain the activity and the
energy involved)
What happens when large amounts of kinetic energy gets transformed into heat energy and delivered to a small area of
an object (such as on the wooden dowel rod)?
Using the Particle Model, describe the difference between an object at a low temperature and an object at a high
temperature?
Can ‘temperature’ be transferred to an object? Explain
What is conduction, and why is the thermal conductivity of a substance an important property that must be
considered when working with the substance?
What is convection, and how is it different from conduction? What causes convective currents to begin in liquids and
gases?
What are the two different types of waves?
What are the two different forms of waves? Give an example of each (Think about the slinky
and the string lab)
How does a mechanical wave pass through matter?
.How is the energy carried by mechanical waves through a substance different from the heat
energy in the substance?
