Q

How is static electricity created?

A

When certain materials rub against each other

18
Q

What is current electricity?

A

The flow of electrons from one place to another carrying electrical energy

19
Q

What is a force?

A

A force is a push, pull or twist applied to an object

20
Q

What is force measured in?

A

Newtons (N) using a newton meter

21
Q

When do contact forces occur?

A

When the object transmitting the force is in contact with the object receiving the force

22
Q

What are non-contact forces?

A

A force that doesn’t require contact and is usually done via magnetism or gravity

23
Q

What is the equation for working out force?

A

F=ma

24
Q

What is the equation for working out mass?

A

m=F/a

25
Q

What is the equation for working out acceleration?

A

a=F/m

26
Q

What is mass measured in?

A

Kg

27
Q

What is acceleration measured in?

A

ms^-2

28
Q

What is mass?

A

It is the amount of matter in an object (the mass of an object doesn’t change on Earth your mass is the same as it would be on the Moon)

29
Q

What is weight?

A

It is the effect of gravity on the mass of an object (the force of gravity on Earth causes objects to accelerate down at a rate of 10ms^-2)

30
Q

What is friction?

A

It is a force that occurs when two objects rub together

31
Q

What is the force that pushes an object forward?

A

Thrust/push

32
Q

What is the force that pushes an object backwards?

A

Drag/friction

33
Q

What is the force that pushes an object down?

A

Gravity/weight

34
Q

What is the force that pushes an object up?

A

Support/air resistance

35
Q

What is the shape of DNA?

A

A twisted ladder (double helix)

36
Q

What is the structure of DNA?

A

It is made up of repeating units called nucleotides

37
Q

What is the location of DNA?

A

The nucleus of a cell

38
Q

What bases pair with each other (DNA)?

A

A+T C+G (straight lines and curvy lines)

39
Q

What is sexual reproduction?

A

It means there are two parents and genetic mixing/not cloned

40
Q

What is asexual reproduction?

A

There is one parent and identical offspring/clone
