MYP Sciences (Physics) – Year 9 Student Name:

Newton’s Laws of Motion – Falling Bodies Investigation

Criterion B: Inquiring and designing

Criterion C: Processing and evaluating

Statement of inquir

Newton’s ! laws of motion ma"e it #ossi$le to #redict t%emotion of a $od if t%e forces acting on t%e $od and t%emass of t%e $od are "nown&

You have studied Newton’s laws of motion, now you need to alyyour !nowled"e to the situation of a fallin" #ody$

[Please note that the word ‘body’ is often used by physicists insteadof ‘object’ – we won’t be looking at any falling human bodies in thisinvestigation!]

'our (as"

You will desi"n your own investi"ation for this assessment$

%he #ody that you use could #e any num#er of thin"s:

a ball a parachute a paper helicopter a stone

a balloon an apple if you are ewton"# the list isendless$

&lso, remem#er that the #ody could #e fallin" throu"h somethin"other than air – it could #e fallin" throu"h a li'uid such as water oroil$

Net, thin! of the varia#les that could #ecome the #asis of yourinvesti"ation:

$ass %urface &rea 'elocity (eight )ength

*ind of )i+uid ,istance &cceleration %peed-ime

For criterion B you will formulate a testa#le hyothesis (research

'uestion) and elain it usin" scientic reasonin"$ You must desi"na fair test i$e$ the indeendent varia#le is chan"ed, the deendent



varia#le is measured and everythin" else is controlled$

• %o have su*cient data you should have a least + dierentvalues of your indeendent varia#le and ta!e reeatedmeasurements of your deendent varia#le

• Your hyothesis should #e elained fully #y referrin" to

Newton’s laws of motion$

For criterion C you will collect and transform data from theeeriment into a ta#le and a "rah$ %hen you must interret thisdata and elain the results of the investi"ation usin" scienticreasonin"$

• %he "rah and ta#le should #e resented in the re'uiredformat, any calculations done usin" the data should #e donecorrectly and clearly elained

• You should refer #ac! to the hyothesis you made in your lan

– were you correct- .hy/ why not-• You should consider the stren"ths and wea!nesses of the

method you have used and su""est imrovements to themethod or follow0u investi"ations$
