Why Study Physics?

What is Physics?

Physics is a  science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics (from the Greek physikos) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels.

Physics is the natural science that studies matter, its fundamental constituents, its motion and behaviour through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.

 

 

What is Science?

Science is the systematic study of the structure and behaviour of the physical and natural world through observation, experimentation, and the testing of theories against the evidence obtained.

Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

The word science comes from the Latin “scientia,” meaning knowledge.

 

What is the Scientific Method?

 

 

 

 

What is psudeoscience?

May be an image of text that says "Science Willingness to change with new evidence Pseudoscience Ruthless peer Fixed ideas review Takes account of all new discoveries No peer review Invites criticism Selects only favourable discoveries Sees criticism as conspiracy Verifiable results Limits claims of usefulness Non-repeatable results Claims of widespread usefulness Accurate measurement "Ball-park" measurement httsp//a/oteoo http://perceptivereality. weebly. com/"

What can I do with my Physics degree?

2022, Worked Examples

Charge moving through magnetic and electric fields

The magnitude of the force created by the electric field is given by

FE = Eq

FE = EQ (using the values in this question)

The magnitude of the force created by the magnetic field is given by

FM = Bqv

FM = BQv (using the values in this question)

 

Q could be +ve or -ve.

If Q is +ve, then:

    • the electric field will exert a downward force on Q
    • the magnetic field will exert an upwards force on Q (from Fleming’s Left Hand Rule)

This could still create the motion indicated in the diagram, however FM would need to be smaller than FE.

FM < FE

BQv < EQ

v < E/Q

If Q is –ve, then:

    • the electric field will exert an upwards force on Q
    • the magnetic field will exert a downwards force on Q (from Fleming’s Left Hand Rule)

This could still create the motion indicated in the diagram, however FM would need to be larger than FE.

FM > FE

BQv > EQ

v > E/Q

Which is answer D

Extra Questions on Linearisation

 

We are always trying to put the equation in to the form:

y = mx + c

 

 

a) p = mv

p/v = m

p(1/v) = m

m = p(1/v)

So to get a straight line graph we will plot m against 1/v

Gradient will be p.

c = 0
Therefore intercept will be (0,0)

b) T = 2π √(L/g)

T² = 4π² (L/g)

T² = (4π²/g)L

So to get a straight line graph we will plot T² against L

Gradient will be 4π²/g.
Thus g can be found from g = 4π²/(gradient)

c = 0
Therefore intercept will be (0,0)

c) s = ½at²

s = ½at²

So to get a straight line graph we will plot s against t²

Gradient will be ½a
Thus a can be found from a = 2 × (gradient)

c = 0

d) n = (sin i) / (sin r)

(sin r)n = (sin i)

(sin i) = n(sin r)

So to get a straight line graph we will plot (sin i) against (sin r).

Gradient will be n.

c = 0
Therefore intercept will be (0,0).

e) 1/ƒ = 1/u + 1/v

(1/u) = (–1)(1/v) + (1/ƒ)

(1/u) = (–1)(1/v) + (1/ƒ)

So to get a straight line graph we will plot 1/u against 1/v

Gradient will be -1.

c = (1/ƒ)
Thus intercept will be (0,(1/ƒ))

ƒ can be found from ƒ = 1/(gradient)

Answers to Practical PR3

MarkSchemeS4P03_updated

Common Mistakes made were:

  • forgetting units in table headings

 

Graph

  • not labelling axes correctly (with units)
  • poor scales
  • not differentiating the two types of points
  • poor best fit curve
  • working for gradient not shown on the graph (large triangle and coordinates of end-points stated)

 

Three common shapes of graph are:

Your description of the graph m
ust allow the reader to differentiate which one you are referring to.

A increases as B increases.

C is directly proportional to D

E is linearly related to F.

Reminder:

Gradient = Δy/Δx

Resistance = y/x     i.e  R=V/I

y/x ≠ Δy/Δx (except for a straight line passing through (0,0).)

YDSP 2022

Dear Sec 4 students,

Invitation to Participate in the Young Defence Scientists Programme (YDSP) World of Science (WOS) Modules 2022

The YDSP WOS 2022 is now open for student applications.

There are 7 exciting WOS enrichment modules this year! The modules are specially designed for IP4 to IP5/JC1 students. To help you and your students better understand the modules, please refer to the attached file ‘YDSP WOS 2022 Module Synopsis’ for more details.

In view of the current COVID-19 situation and the safe management measures in place, the modules will be conducted via physical and/or virtual sessions. DSTA will continue to monitor the COVID-19 situation. If necessary, all modules will be conducted via virtual platforms. The final arrangement will be confirmed with the shortlisted students nearer the date.

A Certificate of Participation will be given to students who achieve 100% attendance for the modules. Please note that students may select up to three modules according to their preference. If selected, they will only attend ONE module.

Please take note of the dates of each module and ONLY apply if you are able to fully commit to the stated dates. In the event that you are selected for the module but decide to withdraw from the module due to any reason or fail to attend all the sessions, it may adversely affect future scholarship or programme application with DSTA.

Please also note that WOS 2022 is only open to Singaporeans.

Please click on this link to submit your application by 21 Jan 2022.

Advanced Physics (modified)Team-based Investigation Project (mTIP)

The scaled-down mTIP will now be conducted in Groups of 2 (from the same class) or done individually.

The project can be an experiment or research on a physics phenomena.

Both options will require submission of a report (PowerPoint Slides) and a presentation.

The Task

Option 1: Experimental Practical

Design and conduct an experiment to investigate any suitable physics phenomena of your choice.

You will need to plan an experiment and let Mr Shone know what physics equipment you wish to borrow from the lab – drop him an email ASAP.

 

Option 2: Research

Choose a topic of suitable difficulty  and suitable depth to investigate on your own.

The topic must not be something we have already looked at as part of the Advanced Physics syllabus.

 

The Presentation

The presentation must be between 10 – 15 mins and everyone in the group must present.

The Slides are likely to include the following to be covered within the stipulated time:

For Practical Projects

      • Brief literature review (theory)
      • Experimental setup and brief procedures
      • Results
      • Analysis
      • Conclusion
      • Brief reflections and key takeaways

For Theory Projects

      • Detailed literature review ( of the topic). You will not be expected to talk on every slide as there is unlikely enough time within the presentation period. Thus summary slides might be useful at points.
      • history of the discovery
      • background information on the key scientists involved

All presentation will end with a short Q&A session.

 

Rubrics

1A: CONTENT (Experimental Project)                                        {15 marks}
