Flashcards in Vectors and Projectiles Deck (16):

1

## Examples of scalar quantites

### mass, volume, speed, distance

2

## examples of vector quantites

### force, velocity, acceleration, displacement

3

## vectors represented by

### putting an arrow above the letter symbol

4

##
the length of the arrow represents

the direction of the arrow represents

###
the magnitude

the direction on the vector

5

## the sum of two vectors is called

### a resultant

6

## vectors are added

### head to tail

7

## what are the 2 components of a single vector can be broken down into

### a horizontal and vertical compnent

8

## a projectile is

### any object that is projected by some means and continues in motion by its own inertia

9

## a projectile can be broken down into

### a horizontal and vertical component

10

## Horizontal component (4) (projectiles)

###
- if no friction, velocity is constant

- object moves an equal distance each s

- no acceleration

- d=v(average)t

11

## Vertical component (5) (projectiles)

###
- force of gravity acts upon it

- if no air resistance, free fall

- acceleration is uniform and is g

- velocity is constantly increasing

- d=1/2 gt^2

12

## Projectiles launched horizontally (if neglecting F air and friction) will experience

### gravity (vertical)

13

##
Projectiles launched at an angle

with no gravity would follow

### a straight line

14

## Projectiles launched at an angle with gravity

### falls beneath this straight line with the same vertical distance as if it fell from rest

15

##
Projectiles:

horizontal velocity is

### the same everywhere
