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
