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

16

Projectiles:
vertical velcocity

changes as in free fall
