App Of Forces

Question 1

If planes up thrust is higher than the weight of plane what happens

Answer 1

Plane goes up

Question 2

What is hookes law

Answer 2

The extension of a spring is directly proportional to the force applied provided that limit of proportionality isn’t exceeded

Question 3

If 2n makes 10cm extension what will 6n make

Answer 3

30cm extension

Question 4

What is the moment

Answer 4

Turning effect of a force around a fixed point called the pivot

Question 5

How to calculate moment

Answer 5

Moment = force x perpendicular distance from pivot (m=fd)

Question 6

What two directions can a moment go

Answer 6

ACWM AND CWM

Question 7

If weight down is 50N and distance from pivot is 10cm what is moment

Answer 7

50 x 10= 500N/cm

Question 8

Answer 9

Newtons

Question 10

What is a force

Answer 10

A push or a pull motion

Question 11

How to calculate force

Answer 11

Force= mass x acceleration

Question 12

How to find force in spring constant

Answer 12

Force applied= spring constant(K) x extension (e)

Question 13

How to calculate moment

Answer 13

Moment = force x distance from pivot

Question 14

What is equilibrium

Answer 14

ACWM=CWM
FD=FD

Question 15

How to calculate pressure

Answer 15

Pressure= force/area

Question 16

Answer 17

1000n/cm

Question 18

If spring constant is 4 and extension is 6 what is force applied

Answer 18

4x6 =24

Question 19

If pressure is 5pa and force is 20n what is area

Answer 19

5pa= 20/A = 5 x 20=a =100cm2

Question 20

If mass = 5kg and volume. Is 20cm3 what is density

Answer 20

50N/20=2.5N/cm2
