Q

Will inertia of an object cub age if it goes to the moon

A

No objects will stay in motion unless acted on by another force sense gravity affects weight not the mass

Q

What is Newton’s first law motion

A

Law inertia, objects at rest tend to stay at rest, objects in motion to stay in motion unless acted on by an outside force

Q

What is support force

A

The force acting against gravity, normal force

21
Q

What formula is given by Newton’s second law

A

Force= m X a

22
Q

The acceleration due to gravity is

A

10/m/s/s

23
Q

How are acceleration and net force related

A

When force increases so does acceleration

24
Q

How is mass of an object related to its acceleration

A

When mass increase
Acceleration decrease
Curving down slope

25
Q

What is friction

A

A force that opposes motion

26
Q

What is weight

A

Is amount of force generated by the effect of gravity in the mass

27
Q

What is mass

A

Mass is amount of matter in an object

28
Q

Is mass or weight a force

A

Weight is a force mass is not

29
Q

What will change when you go to the moon

A

Weight

30
Q

Acceleration formula

A

A= f/m

31
Q

How to convert newtons weight into mass

A

‘N= kgX 10 m/s/s

So n/ 10 m/s/s = kg

32
Q

If force us doubled then the acceleration will

A

Double

33
Q

If mass is doubled then the acceleration will

A

Be halved

34
Q

What is the weight of a 90kg man

A

90kg X 10m/s/s = 900N

35
Q

What is another formula for acceleration

A

A= vf-vi/t

36
Q

Centripetal acceleration

A

Moving constant velocity in circle, feel like moving to the outside because of inertia but acceleration is pointing to the inside

37
Q

Gravitational force formula

A

M + M2/ d squared

38
Q

Weight formula

A

Gravity X mass in kg

10m/s/s X kg

39
Q

Formula for force

A

M X a

40
Q

What is a force

A

Push in or pull in a certain direction

41
Q

What kind of number is deceleration
