Forms of Kinetic Energy Guided Reading
Mission 1
1. On what two things is kinetic energy dependent? Mass and velocity
2. What is the equation for mechanical kinetic energy? KE = ½ mv2
3. Even though CME’s have very small masses, they can still have serious effects on space crafts and their
crews. Why? CME’s have very high velocities, so they have a great deal of kinetic energy that can
destroy satellites, corrupt computers, or even injure living cells and damage DNA if they impact.
4. What are particles that make up a substance always doing? They are always vibrating, stretching and
rotating
5. What is thermal energy? Thermal energy is the total energy within a substance.
6. What do we measure when we measure temperature? We are measuring the concentration of thermal
energy.
7. What is electrical energy? It is kinetic energy that results from movement of charges.
8. How is sound energy transferred? Sound energy is transferred by vibrations passed along through the
air.
9. How fast do electromagnetic waves travel? Electromagnetic waves travel at the speed of light.
10. What types of properties do electromagnetic waves have? Do they need a medium through which to
travel? Electromagnetic waves have electric and magnetic properties. They do not need a medium.
11. What is the unit for all forms of energy? The joule (J)
12. What is work? Work is the energy needed to move an object a certain distance using a force.
13. What is the equation for work? W = F x d The unit for work is the joule because work is a form of
energy.
14. What is power and what is its unit? Power is the rate at which work is performed, or how much work in
how much time. Its unit is the watt (W)
15. Where did the term horsepower come from? The term horsepower was first used as a way of comparing
the power of early steam engines to that of horses. James Watt based the measurement of horsepower
on the estimated amount of coal that could be lifted by a horse.
16. What is the Law of Conservation of Mass? The total mass of the reactants equals the total mass of the
products. Matter cannot be created nor destroyed; it can only change forms.
17. What is nuclear potential energy? Nuclear potential energy is the energy stored in the bonds of the
subatomic particles.
18. How is nuclear potential energy released? Energy is released by either splitting or fusing atoms through
the process of fission and fusion.
