*force
-a push or  pull
-acts on a object
-Vectors (direction + magnitude)
*Mass
- a measure of the amount that makes upon an object
-Units:kg
*Weight
- The measurement of the pull of gravity on an object
-Units: N
-Weight=(mass)(grav.)
*Gravity
-pulls 2 objects w/ mass towards each other
-9.8 on earth
-Units:m/s^2
*Newtons 2nd law
-F=ma
*Friction
-Always resists motion
-Units: N

kepler's first law means that planets move around the Sun in elliptical orbits.
Kepler's second law states that a planet moves in its ellipse so that the line between it and the Sun placed at a focus sweeps out equal areas in equal times.
kepler's Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi major axes of their orbits.

potential energy is the energy that a body has as a result of its position with relation to others, internal tensions, electric charge, and other variables.

Kinetic Energy is a form of energy that an object or particle has by its reason of motion.

-change in position

- a yoyo before it is released
- a book on a table before it falls
- a child on top of a slide
- water that is behind a dam

1st law - a body at rest unless acted upon
Example - someone kicking a soccer ball

2nd law -the force on an object is equal to its mass times its acceleration
F=m•a

3rd law - For every action, there is an equal and opposite reaction.
Example -car accelerates forward because the ground pushes forward on the drive wheels, in reaction to the drive wheels pushing backward on the ground.

3rd law- Newtons third law is the law of equal and opposite reactions. It states that for every action there is an equal and opposite reaction pushing back. For example if  you are pushing a car there is an equal force pushing back at you

- Its a property of mass
- Attractive force between any two objects that have mas
- Gravity here on Earth is 9.8 m/s

Weight
- Its used to describe the gravitational force that acts on an object
- Usually measured in Newtons (N)
- An equation to find weight is W=mg (Weight = Mass x Gravity)

Newtons Law of Gravitation
- Its used to calculate the force of gravity acting between any two objects

Motion- Change in position

Speed- How fast an object is
moving

velocity- Is the speed plus the direction the object is moving

Acceleration- how velocity is changing over time

Calculations- Speed=d/t, Velocity=d/t, Acceleration=v/t

As radius increases, force decreases by a factor of r2

Very common for forces at a distance
