Motion 1.1 Frame of Reference

Frame of Reference

Summary (1): Frame of reference is the way you view an object in motion. Depending on where you view an object, it may be moving differently. For example, if a car was moving in a positive direction and there is two people on different sides of the road, then they would view the car as moving in different directions. In reality, they are both correct however are viewing from different frame of references.

Force 5.1 Field Strength and Force

Field Strength and Force

summary: 

There are three major types of fields: gravitational fields, electric fields, and magnetic fields. These fields apply force on all objects in the universe that we know of. No matter the field, something that always applies is: the stronger the field is, the more force it can apply to an object.

Motion 2.2 Velocity

Motion 2.2 Velocity

Summary:

Velocity is total change in position divided by the amount of time. ( Displacement/Time=Velocity ) Velocity does not show the total distance traveled like Displacement. Velocity is a Vector Quantity.

Position vs Time Graph

SUMMARY:

Graphing position vs time and velocity vs time allows us to easily view and interpret data.  The visual data representation can be used to investigate and compare the motion of objects. Understanding these graphs, and being able to create these graphs, is a huge step towards understanding the physics of motion in our universe. (Masonps.com)

5.3Gravitational Force proportional to mass

The gravitational force of an object is mathematically proportional to its mass.  We know that F = MA.  In the case of gravitational forces, we use the same equation.  Specifically the equation would follow this logic.  Gravitational Force (also known as weight) = The mass of the object multiplied by the acceleration due to the gravitational field strength.  In a simplified equation dealing with an object on earth, it would simply be expressed as Weight= mass x gravitational acceleration (10m/s/s).  In summary, on earth, if you multiply the mass of an object
