Motion and Energy

1. Motion and Energy Energy

2. Energy, work, joules • ___________________ is the ability to perform ______ and is measured in units called Newton-meters or _______________.

3. potential energy 2. The energy that is stored in the position or the structure of an object is called ____________________ _________________.

4. Chemical potential Examples: Battery Match stick Food Drinks 3. _______________ ________________ energy is the energy stored in the links between atoms and molecules.

5. Elastic potential Examples: slingshot trampoline bow and arrow rubber band 4. _______________ ________________ energy is the energy stored by something that can stretch or compress.

6. gravitational potential Examples: child on a slide books on a shelf boulder on a hill picture hanging on wall 5. The energy an object possess due to its position above Earth’s surface is called ______________ ________________ energy.

7. more 6. The greater an object’s weight and height above the ground, the _______________ gravitational potential energy it gains.

8. Kinetic energy 7. ______________ ___________ is the energy of a moving objects or motion. A rollercoaster is an example of kinetic energy as it moves along its tracks.

9. velocity, mass 8. The amount of kinetic energy depends on the objects ______________ and its _________________. The faster an object is moving the more kinetic energy it has. The same applies for the object’s mass. The more mass an object has, the more kinetic energy it has.

10. Heat, electricity, sound, light 9. Like potential energy, kinetic energy can take many forms:______________, _________________, _______________, and _________________ are types of kinetic energy.

11. Heat energy is kinetic energy in the vibration of particles.

12. Electricity is related to the kinetic energy of electrons.

13. Sound energy is kinetic energy of particles as they move in waves.

14. Light energy is kinetic energy that moves in the form of rays.

15. created, destroyed 10. Energy cannot be __________________ or ______________; it can only change form. The theory is called the law of conservation of energy.
