Flashcards in Physics- Gravitational Force Deck (15):
1

Gravitational force that

Earth exerts on all objects around it

2

Ground is the surface

Of the earth and the force that is attracting objects towards the center of the earth's force of gravity or gravitational force

3

If not for the

Attractive force of gravity, all objects on the surface of the earth would float off into space

4

Also gravitational force between

The earth and moon, and between the sun and all planets surrounding it

5

Measured in

Newtons (N)

6

Size if forces depends on

The masses of the two objects- bigger masses of the two objects, larger gravitational force between them
Distance between two masses- shorter distance between two masses, larger gravitational force between them

7

Mass of an object is

The amount of matter in an object
Kilograms (kg)

8

Mass stays

Constant and doesn't change even if an object moves anywhere in the universe

9

Weight of an object is

The force with which an object is attracted by gravitational towards the center of the earth or another body

10

Weight is calculated by

Multiplying the mass of an object in kilograms by the force of gravity

11

Gravitational force of earth is

9,8 m/s*squared*

12

Gravitational force on the moon is

1,6m/s*squared*

13

Weight depend on

The size of the gravitational force

14

Weight =

Mass x gravitational force

15

W= m x g

W= weight of object in Newtons
M= mass of objects in Kilograms
G= gravitational acceleration in m/s*squared*
