A Level Physics Summer Independent Learning Activity

Welcome to second year A Level Physics, please complete the following tasks ready for your first day

back at New College. You can either write on the document electronically, print the document out or

write your notes and answers on paper to bring in for your first lesson in September.

Part 1: Section A

Task 1. Read through your class notes on Circular Motion and then watch and make extra notes on

the video linked below: ‘Circular motion basics’ –

Task 2. Read through your class notes on Centripetal Force and Acceleration and then watch and

make extra notes on the video linked below ‘Forces and circular motion’–

Both tasks, 1 and 2, should take a minimum of 1 hour each.

Part 2 – Section B.

Task 1: Use your notes and the Kerboodle textbook to answer the questions on the 4 topics in

Section B.

Task 2: Go to the Year 12 page of Moodle and, in the bottom section, entitled Y12 Summer task, use

the mark schemes to mark and correct your work.

Task 3: Use your notes and the Kerboodle textbook to answer the exam style questions in section B.

Task 4: Go to the Year 12 page of Moodle and, in the bottom section, entitled Y12 Summer task, use

the exam style question mark scheme to mark and correct your work.

This task should take you approximately 1 and a half hours.

Part 3 – Revision.

Now you have the information you need and have practiced the types of exam questions you will

answer on these topics, you will need to learn all the definitions in your notes and how to apply your

knowledge.

Choose one of the following tasks to help you start your revision:

1. Go to Quizlet: https://quizlet.com/en-gb and make a set of flashcards to help you revise.

2. Make a set of flash cards on card or paper.

3. Create a mindmap showing how all the content is linked

4. Create a mindmap online at: https://bubbl.us/

This task should take you approximately 1 and a half hours.

After studying these 2 topics, you will sit an assessment in September based on this work.

Section B

Exam Style Questions.

1 (a) What is meant by the term angular velocity? What is the unit? (2)

(b) An electric motor is turning at 50 Hz. Calculate its angular velocity (1)

2 A hammer thrower whirls a 2.0 kg hammer on the end of a rope in a circle of radius 0.80 m. The hammer took 0.60 s to make one full rotation before it was released. Calculate

(a) The speed of the hammer just before release. (2)

(b) The centripetal acceleration. (2)

(c) The centripetal force (1)

(d) What is the path of the hammer when it is released? (1)

3 The maximum speed for no skidding of a vehicle of mass 1500 kg on a roundabout of radius 20 m is 9.0 m/s. What is the centripetal force acting on the vehicle?

(2)

4 What provides the centripetal force as a car goes round a bend? (1)

5 As the car goes round a left-hand bend the occupants feel that they are being moved to the right. Explain why it’s wrong to call the force “centrifugal force”.

(3)

6 A bob-sleigh in the Winter Olympics has a speed of 35 m/s as it goes down the track. A bend has a radius of 20 m.

(a) To what angle should it be banked to enable a bob-sleigh to go round the bend and

stay on the track? (v2 = gr tan )

(2)

(b) Explain whether a single person sled would perform in the same way as a two person bob-sleigh

(2)

7 The big wheel at a fairground has a radius of 12.0 m and rotates once every 6 seconds. Calculate:

(a) The speed of rotation of the perimeter of the wheel (2)

(b) The centripetal acceleration of a person on the perimeter (2)

(c) The force acting on a person of mass 72 kg at the highest point (2)

Total = 25 marks
