Here are the answers to the questions as promised.  Now correct the work that you blogged.  Two options to do this:

1.    Send another e-mail to your blog called “Corrections to…” and highlight the changes in a different colour.

2.    Edit your blog post and make the changes in a different colour.

Cheers,

Mr B

Dear 10.2W,

Welcome to your second e-lesson!  I know it’s a day early but I’m probably going to be without internet tomorrow…

This e-lesson consists of 3 objectives; 1.23, 1.25 and 1.26. 

  Instructions for Objective 1.23

1.    1.23.  Learn the formula and units.  Have a go at the quick questions (the five animations attached)

2.    1.23 Moments Questions.  Forward this e-mail to your blog.  Type your answers under the questions. 

3.    Answers to step 2 will be sent separately.  Don’t look at them until you’ve done the work!

·         1.23 recall and use the relationship between the moment of a force and its distance from the pivot: 

moment = force × perpendicular distance from the pivot

·        A moment is a turning force

·        It depends on the size of the force and the perpendicular distance from the pivot

M = F x d

 

M = moment (Nm)

F = force (N)

d = perpendicular distance from the pivot (m)

Worked example

Image001

M = F x d

M = 1 x 5

M = 5Nm

Quick questions. 

(No need to type anything - just open the animation, choose your answer and then check your answer)

•        1.14 recall and use the relationship between unbalanced force, mass and acceleration:           

force = mass × acceleration           

F = m × a
