An average of all speeds over a given time
What is average speed?
The concept of center of mass
What did the Greek Physics introduce?
The science of movement
What is physics?
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of an object
What is newton's 2nd law?
For every action there is an equal opposite reaction
What is Newtons 3rd law?
Distance divided by Time
How do you calculate average speed?
The unique point where the weighted relative position of the distributed mass sums to zero
What is center of mass?
An object will keep at motion until collided with another object than it will stop or slow down
What is Newton's 1st law?
Force divided by Mass
How do you find acceleration?
Where the force exerted is the action and the force experienced as a consequence is the reaction
When does Newton's 3rd law happen?
The change in distance over a specific amount of time
What is Speed?
When formulated with respect to the center of mass
When are calculations in mechanics simplified?

The law of action and reaction
Units of distance or time
What are Speed Units measured in?
The barycenter
What is center of mass in astronomy?
It will continue to move until it is acted on by an unbalanced force
What will happen to an object if it is put to motion in space?
As one value increases, so does the other
What does directly proportional mean?

What is a force and what do they come in?
No movement
What does a straight line on a motion graph mean?
What is a reference of center of mass?
Tendency to keep doing what they’re already doing and resist changes in motion
What is inertia?
As one value increases, the other decreases
What does inversely proportional mean?
Magnitude and Direction
