Kinetic energy is energy that is currently active or in motion

# data[].attributes.body
equation W=mg
Describes the gravitational force that acts on an object
Measured in N

# data[].attributes.body
an object will not change its motion unless a force acts upon it.

# data[].attributes.body
Attractive force between any two object that have mass.
Acceleration due to gravity on Earth is 9.8m/s.

Weight
Measured in N
W=mg
m=mass
g=acceleration due to gravity

Newton's Law of Gravitation
Equation used to calculate the force of gravity acting between any two objects
F=G*M1*M2/r^2
G=Universal Gravitation Constant=6.673*10^-11
M1 and M2=Mass of object
r=radius from then center of mass

# data[].attributes.body
Motion - speed and velocity

# data[].attributes.body
Describes how planets move around the sun in ellipses

# data[].attributes.body
f=ma

# data[].attributes.body
Force- push or pull on an object

# data[].attributes.body
kinetic energy is the energy of a moving object.

# data[].attributes.body
There is always an equal to opposite reaction to every action

# data[].attributes.body
Takes the same amount of time to travel from one point to another as well as it does for any other point

# data[].attributes.body
Potential Energy is the energy stored in an object - the energy of position - can be used later on.

The more mass an object has, and the higher it is, the more potential energy is has.

As potential energy increases, kinetic energy decreases. Vice versa.

# data[].attributes.body
The faster the object moves the more kinetic energy is produced.

# data[].attributes.body
It is further and longer and the period must be measured in earth years.
T^2=a^3

# data[].attributes.body
v= distance/ time

# data[].attributes.body
There are 5 types of kinetic energy including radiant, thermal, sound, electrical, and mechanical.

# data[].attributes.body
* someone kicking a soccer ball
*a car getting crashed into
*dominoes

# data[].attributes.body
Potential energy due to an objects position .

PE -> Ug
PE = mass x gravity x height

# data[].attributes.body
d= velocity * time

# data[].attributes.body
An object has the most kinetic energy when it's movement is the greatest.

# data[].attributes.body
acceleration the significance of + and - is the direction of the motion

# data[].attributes.body
Potential energy due to compression or expansion of an elastic object

Us = 1/2 kx^2
k - spring constant
x - how far the spring was compressed or stretched

# data[].attributes.body
speed- how fast something is going

# data[].attributes.body
*when you can hit a baseball farther away then you can hit a heavier ball.

# data[].attributes.body
Mass= How much of the object there is

# data[].attributes.body
Potential energy stored within chemical bonds of an object

# data[].attributes.body
velocity- how position is changing over time

# data[].attributes.body
Weight= how much gravity the object will take up

# data[].attributes.body
*if you are the only one on a row boat and you go to the very tip and stand the back of the row boat will come up.
* a person skateboarding

# data[].attributes.body
There is a equation to calculate kinetic energy and it is
kinetic energy=1/2 (mass of object)(velocity of object)^2
KE=1/2 mv^2

# data[].attributes.body
Friction- always resists motion

# data[].attributes.body
Gravity- property of everything with mass and pulls two objects with mass towards each other
