A force is a push or pull that acts on an object due to the interaction with another object. |
|
What is a force? |
|
|
|
All forces between objects are either:
- contact forces - the objects are physically touching
- non-contact forces - the objects are physically separated. |
|
What is the difference between contact and non-contact forces? |
|
|
|
Examples of contact forces include friction, air resistance, tension and normal contact force. |
|
What examples are there of contact forces? |
|
|
|
Examples of non-contact forces are gravitational force, electrostatic force and magnetic force. |
|
What examples are there of non-contact forces? |
|
|
|
Students should be able to describe the interaction between pairs of objects which produce a force on each object. The forces should be able to be represented as vectors. |
|
What is the interaction pair between a book being pushed across a table, where a force is produced on each object? |
|
|
|
Force is a vector quantity. |
|
What is meant by the term ‘vector quantity’ in terms of forces? |
|
|
|
Vector quantities have magnitude and an associated direction. |
|
What do all vector quantities have? |
|
|
|
A vector quantity may be represented by an arrow. The length of the arrow represents the magnitude, and the direction of the arrow the direction of the vector quantity. |
|
How is an arrow used to represent a vector quantity? |
|
|
|
Scalar quantities have magnitude only. |
|
How are scalar quantities different from vector quantities? |
