Electric And Normal Magnets Definitions

Question 1

What is force

Answer 1

When you pull or push something.forces occurs all the time
Eg 🔷when blood pumps around in you’re body

🔷when you write you use force to push you’re pen on paper

Question 2

What is contact force

Answer 2

a force that acts only between objects that are touching

Eg🔷when you hit something or when something hits the ground

Question 3

What is gravity

Answer 3

the force of attraction that exists between any two bodies in the universe

Eg🔷 when you stand you stay on the ground other than flying off or when you drop a tennis ball, it speeds up as it falls through the air because of the force of gravity pulls it towards the Earth

Question 4

What is a non-contact force

Answer 4

a force that acts between objects even though the objects are not touching

Eg🔷 Gravity and weight

Question 5

What are magnetic forces

Answer 5

the force that acts between magnets

Eg🔷when you hover one or more magnets above another they stick

Question 6

What is a electrostatic force

Answer 6

a non-contact force of electric charges at rest.

Eg🔷The electricity that builds up on plastic rulers, balloons and the Van de Graaff generator

Question 7

What is a permanent magnet

Answer 7

a magnet that retains its magnetic effect for many years

Eg🔷 iron,nickel and colbolt which are a natural permanent magnet and alloys

Question 8

What are alloys

Answer 8

a mixture of a metal with a non-metal or another metal

Question 9

What is a temporary magnet

Answer 9

a magnet that stays magnetic only while it touches a permanent magnet and when they are separated they lose there magnetism

Eg🔷 paperclips

Question 10

What is the North Pole

Answer 10

the end of the magnet that, when free to rotate, points to the North Pole

Question 11

What is a South Pole

Answer 11

the end of the magnet that, when free to rotate, points to the South Pole

Question 12

What is relpolsion

Answer 12

an opposing force

Eg🔷 when two north or south sides of a magnet brought together they repel from each other which is called repulsion

Question 13

What are domains

Answer 13

Small mini magnets are called domains if they face the same direction they will act as a magnet

Question 14

What is a magnetic field

Answer 14

a map of lines showing the size and direction of a magnetic force.

Question 15

What are atoms

Answer 15

a very small particle that makes up all things

Answer 17

very light, negatively charged particles inside an atom.

Question 18

What is a negative electric charge

Answer 18

the charge on an atom or object with more electrons than protons

Question 19

What are protons

Answer 19

tiny, but heavy, particle found in the nucleus of an atom.

Question 20

What is a positive electric charge

Answer 20

the charge on an atom or object with fewer electrons than protons

Question 21

What are neutrons

Answer 21

tiny, but heavy, particles found in the nucleus of an atom

Question 22

What does neutral mean

Answer 22

having the same number of protons and electrons

Question 23

What does static electricity mean

Answer 23

a build-up of charge in one place

Question 24

What is an insulator

Answer 24

materials that do not allow electric charge to flow through them

Eg🔷 through rubber and air

Question 25

What does conductors mean

Answer 25

materials that allow electric charge to flow through them

Eg🔷Metals

Question 26

What does lightning rod mean

Answer 26

conductive metal rod, often attached to the top of tall buildings.

Question 27

What does friction mean

Answer 27

the resistance that one surface or object encounters when moving over another.

Eg🔷 when you drag you’re feet across the ground and then you touch something it zaps you

Question 28

What does electromagnets mean

Answer 28

a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.

Eg🔷electricity and x-Ray’s

Question 29

What is mass

Answer 29

a large body of matter

Question 30

What is weight

Answer 30

a piece of metal known to weigh a definite amount

Question 31

What does air resistance mean
