Energy

Question 1

Energy

Answer 1

The ability to do work. Anything that is moving has energy.

Question 2

Kinetic Energy

Answer 2

Energy of motion. EX. a ball rolling

Question 3

Potential Energy

Answer 3

Stored energy. EX. a ball at rest before kicked

Question 4

Mechanical Energy

Answer 4

The energy of motion. It exits as both kinetic and potential energy in a system. EX. riding a bike

Question 5

Solar Energy

Answer 5

Energy from the sun.

Question 6

Thermal Energy

Answer 6

The energy of moving particles in a substance. Thermal energy flows from hotter objects to cooler ones.

Question 7

Conduction

Answer 7

Where the heat energy travels between objects that are in contact. EX. touching the burner transfers heat to the pot

Question 8

Convection

Answer 8

Where fluids such as air or water are heated Expanded and rise displacing and mixing with cooler portions. EX. air or water flow/movement- convection often spreads warm air throughout the oven while a cake is baking, it spreads the air evenly

Question 9

Radiation

Answer 9

Where heat energy is traveling by invisible waves in all directions from the source. EX. sun bathing

Question 10

Friction

Answer 10

When one objects rubs against another. Friction produces heat.

Question 11

Conductor

Answer 11

A material that allows heat or electricity to move through it easily. EX. wire metals

Question 12

Insulator

Answer 12

A matieral that does not allow heat or electricity to move through it. EX. rubber is a good insulator, a kitchen mitt keeps you from getting burned by the hot pan or baking sheet

Question 13

Sound

Answer 13

A form of energy produced by vibrating objects.

Question 14

Vibration

Answer 14

Back and forth motion.

Question 15

Electrical energy

Answer 15

The movement of very small particles in matter.

Question 16

Electric circuit

Answer 16

A complete pathway of conductors that electrons flow through

Question 17

Electric current

Answer 17

A constant flow of electrons through a conductor.

Question 18

Electromagnetism

Answer 18

Creating a magnetic field easy electric wire. You can turn on and off and electromagnet. Example – telephones have electromagnets

Question 19

Light Energy

Answer 19

Only form of energy that can be seen. It travels in waves through certain types of matter such as air, class, water, and even through space.

Question 20

Light Rays

Answer 20

Straight lines light travel through.

Question 21

Reflection

Answer 21

The bouncing back of light rays from a surface.

Question 22

Transparent Medium

Answer 22

Allows light to pass through it easily. Example – it is a clear – window

Question 23

Translucent medium

Answer 23

Materials scatter the light as it passes through so that objects viewed cannot be seen clearly. Example – wax paper and foggy glass

Question 24

Opaque medium

Answer 24

Materials that don’t allow any light to pass through. Example – a desk a shoe, etc….

Question 25

Refraction

Answer 25

The bending of light rays as they move from one material into another material. Example – astronomy class, eyeglasses, camera, telescope, ect….

Question 26

Light spectrum

Answer 26

The light you see is called the light spectrum.

Question 27

Lens

Answer 27

Curved piece of clear glass or plastic that bends light. Example – our eye or eyeglasses

Question 28

Inverted

Answer 28

Upside down – the image on our retina in our eye is inverted in our brain turns image right side up.

Question 29

Convex

Answer 29

A lens that is thicker in the middle then at the edges refracts light rays toward one another.

Question 30

Concave

Answer 30

A lens that is thicker at the edges then in the middle refracts light rays away from one another

Question 31

Magnify

Answer 31

Something that makes images bigger than they really are.

Question 32

Sound

Answer 32

Vibrations

Question 33

Name 4 different types of energy

Answer 33

Solar, chemical, thermal, light, sound, electrical.

Question 34

Name all of the colors in the light spectrum.

Answer 34

Red, orange, yellow, green, blue, indigo, and Violet

Question 35

Open Circut

Answer 35

Energy does not pass through and it will not work properly.

Question 36
