contact and non contact forces Flashcards
What is a vectors quality?
A vector quality is magnitude and direction. This is a force.
What are vector quantities?
force, velocity, displacement, acceleration and momentum.
What is a scalar quantity?
Magnitude and no direction.
What are scalar quantities?
speed, distance, time, mass and temperature.
What are vectors represented by?
Vectors are represented by arrows.
What does the length of the arrow show?
The length shows the magnitude and direction.
What is a force?
A force is a push or pull on an object that is caused by it interacting with something.
What is it called when two objects are touching for a force to act?
When two objects are touching for a force to act it is called a contact force.
What is it called when the two objects are not touching for a force to act.
When the two objects are not touching and a force is to act this is called a not contact force.
What is an interaction?
An interaction is a force produced on both objects.
What is an interaction pair?
An interaction pair is a pair of forces that are equal and opposite and act on two interacting objects.
