Intense physics

For any other physics students I have opened a physics blog. Right now it’s on a queue so were only at the basics because it’s my form of taking notes, but of you ask me questions I’ll do my best to answer. @intensephysics

Speed vs Velocity

Speed measures how fast an object is moving (scalar quantity), Velocity measures both an objects speed and direction (vector quantity).

[intensephysics-blog]

Velocity

displacement over time interval (please note this is AVERAGE velocity, not instantaneous)

[intensephysics-blog]

Speed

Distance traveled over the time frame

Apologies

I'm terribly sorry that I haven't been posting information recently. School has been hectic. Hopefully this blog will be back up and running soon. Please stand by.

Uniform Motion

An object moving at a constant speed, not speeding up or slowing down.

[intensephysics-blog]

Note!

Keep in mind that even if an object begins at a positive position and undergoes a negative displacement that the objects final position still can be positive.

[intensephysics-blog]

Time Frame

A variation of a displacement, except related to time and not position/distance. Most commonly used as the time it takes to get from point A to point B. Calculated as time final minus time initial.

[intensephysics-blog]

Displacement

the difference between the final and initial position. For example if Steve travels 50 feet east and then 50 feet west he travels a distance of 100 ft. total but his displacement is zero.

Position

A position requires three things to be relevant:

1) An origin

2) A distance from the origin

3) A direction from the origin

[intensephysics-blog]

Origin

Fixed reference point

[intensephysics-blog]

One-Dimensional

Occurences along a singular axis. Ie: an elevator in a shaft, a car driving in a straight line

[intensephysics-blog]

Particle Model

The same thing as a motion diagram, except you only need to use a dot instead of drawing the object. Often numbered to show which order the events happen in. The dot itself is called a particle.
