-Examples: speed,distance,mass temperature and time

Question 3

How are vectors represented?

Answer 3

Question 4

what is a force?
what are two types of forces?

Answer 4

-A force is a push or pull on an object that is caused by it interacting with something
-They are either non-contact or contact
-Contact=when two objects have to touching for a force to act eg friction air resistance,tension in ropes ect
-Non-contact if the object do not need to be touching for the force to act eg magnetic force,gravitational force and electrostatic force

Question 5

what is the interaction between two pairs of objects?

Answer 5

-When two objects interact there is a force produced on both objects
-Interaction pair is a pair of forces that are equal and opposite and act on two interacting objects
