Q

Domains

A

Are mini magnets that are inside every object. If they are in order, they magnetise the object, but if they are scrambled, they don’t magnetise the object.

Q

Electro Magnet

A

An electromagnet is a piece of non magnetised iron with insulated wire around it that magnetises and arranges the domains within the iron.

17
Q

Weight

A

The measurement of the mass’s gravitational pull and it is measured in newtons.

18
Q

Newton

A

The measure of force.

19
Q

Air Resistance

A

The force pushing against falling objects.

20
Q

Terminal Speed

A

The speed reached when the air resistance and the force of gravity are balanced, so the falling object cannot go any faster.

21
Q

Atoms

A

Are very small particles that make up all things.

22
Q

Nucleus

A

The roundish structure made up of protons and neutrons that acts as the control centre.

23
Q

Electrons

A

Very light, negative charged particles that move around the nucleus.

24
Q

Negative Electric Charge

A

The negative charge of an atom that has more electrons than protons.

25
Q

Protons

A

Tiny, but heavy particles that make up part of the nucleus. They have a positive electrical charge.

26
Q

Positive Electric Charge

A

The charge of an atom when there are more protons than electrons.

27
Q

Neutrons

A

Tony, but heavy particles that also make up the nucleus. They have no electric charge.

28
Q

Neutral

A

The same number of protons and electrons. The atom has no electric charge.

29
Q

Static Electricity

A

The build up of electricity in one object.

30
Q

Insulators

A

Materials that don’t allow electric charge to flow through them.

31
Q

Conductors

A

Materials that allow electric charge to flow through them.

32
Q

Friction

A

Is the force applied when the surface of an object moves against another surface of the object.

33
Q

Traction

A

A type of friction that assists the movement of an object.

34
Q

Lubricants

A

Substances with large particles that make two objects against each other last longer and have more movement.

35
Q

Fluid

A

Substances that have no shape or form. Examples are Gas and Liquids.

36
Q

Streamlined

A

Shaped so fluid is minimised to the minimum.

37
Q

Alloys

A

A mixture of metals and non metals.

38
Q

Alloys

A

A mixture of metals and non metals.

39
Q

Buoyancy

A

Is the force that pushes the weight of an object on a fluid up.

40
Q

Surface Tension

A

When water particles are holding together, they keep the shape, but if you add soap or detergent, the particles will let go and make a different shape.
