Flashcards in contact and non contact forces Deck (11):
1

What is a vectors quality?

A vector quality is magnitude and direction. This is a force.

2

What are vector quantities?

force, velocity, displacement, acceleration and momentum.

3

What is a scalar quantity?

Magnitude and no direction.

4

What are scalar quantities?

speed, distance, time, mass and temperature.

5

What are vectors represented by?

Vectors are represented by arrows.

6

What does the length of the arrow show?

The length shows the magnitude and direction.

7

What is a force?

A force is a push or pull on an object that is caused by it interacting with something.

8

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.

9

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.

10

What is an interaction?

An interaction is a force produced on both objects.

11

What is an interaction pair?

An interaction pair is a pair of forces that are equal and opposite and act on two interacting objects.
