Flashcards in Gravity/ Free Fall Deck (31):

1

## What has a greater effect, moon or sun

### The moon

2

## Why does the moon have a greater effect on the tides

### Because it's much closer

3

## Hey does a parachute change your terminal velocity

### It slows you down so it makes the fastest you can possibly go, slower

4

## Why does mass not affect the acceleration of falling objects

### Everything falls at 10m/s/s so mass doesn't affect that

5

## When does surface area affect a falling object

### When it is falling fast enough and is big enough then surface area will affect the air resistance causing it to go slower

6

## What is terminal velocity

### When objects stop accelerating and fall at a Constant speed

7

## How are tides caused

### Caused by gravitational effect of the sun and moon

8

## Newton's second law is

### F= m X a

9

## How do you calculate weight into newtons

### Convert to kilograms then multiple by ten

10

## How to calculate speed of a falling object

###
S=d X t

D= 1/2 g t(2)

11

## What is a formula for v

### V=g t

12

## How do you find how far an objects fallen for a certain second only

### D= 1/2 g t(2) for that second and the second before, then subtract the two

13

## How do you calculate how high an arrow will go till it stops going up

###
Divide velocity by ten

Gives you the seconds

Then use d= 1/2 (-10) ( seconds) (2)

14

## How to calculate the distance an object has fallen

### D= 1/2 (g) (t) (2)

15

## How to find velocity when leaving your hand

### Time X 10m/s/s

16

## Another formula for acceleration

### A= f/m

17

## How do you find mass

### M= f/a

18

## What is Newton's third law

### For every action there is an equal and ooposite reaction

19

## What are whisk and opposite forces called

### Action and reaction force

20

## Newton's second law is

### F= m X a

21

## How do you calculate weight into newtons

### Convert to kilograms then multiple by ten

22

## How to calculate speed of a falling object

###
S=d X t

D= 1/2 g t(2)

23

## What is a formula for v

### V=g t

24

## How do you find how far an objects fallen for a certain second only

### D= 1/2 g t(2) for that second and the second before, then subtract the two

25

## How do you calculate how high an arrow will go till it stops going up

###

Gives you the seconds

Then use d= 1/2 (-10) ( seconds) (2)

26

### A= f/m

29

## How do you find mass
