- Paper 6
Forces and Their Effects is examined in Paper 6, Physics 2.
It covers contact and non-contact forces and vectors and scalars, and reducing friction.
Sample questions from Forces and Their Effects
Answer each one closed book first, then open the answer.
-
Contact and non-contact forces
Give an example of two objects interacting through an electrostatic field.
Show the answer
A charged plastic rod attracts small polystyrene balls without touching them. -
Contact and non-contact forces
Give two examples of contact forces.
Show the answer
The normal contact force from a surface and friction between two surfaces. -
Vectors and scalars, and reducing friction
Explain why speed is a scalar quantity but velocity is a vector quantity.
Show the answer
Speed states only how fast something moves, whereas velocity also states the direction of motion. -
Vectors and scalars, and reducing friction
Describe what happens to the friction force at a door hinge after oil is applied to it.
Show the answer
The friction force becomes smaller.
The 2 subtopics
One subtopic is one session. Work down the list.
| Subtopic | What it covers | Questions |
|---|---|---|
| Contact and non-contact forces | Non-contact forces acting through gravitational, electrostatic and magnetic fields with an example of each, contact forces such as the normal contact force and friction, interaction pairs, and why a force is drawn as an arrow. | 11 |
| Vectors and scalars, and reducing friction | Vector and scalar quantities with examples, speed and velocity, mass and weight, distance and displacement, and how lubricants reduce friction in door hinges, engines, bicycle chains and machines. | 11 |
How the guide is worked
Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.
-
Step 1 · Closed book
Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.
-
Step 2 · Open book
Go back to the top. Read each printed answer and write it out in full, including the ones you had right.
-
Step 3 · Closed book again
Same questions, same order, from memory. The gap between pass one and pass three is the session result.
Read the full method, the return schedule and the research behind it.
