Mechanics
Kinetic Energy
Kinetic energy = ½ x mass x velocity squared
(J) (kg) (m/s)
Gravitational Potential Energy (GPE)
GPE = mass x gravitational field strength x height
(J) (kg) (N/kg) (m)
Weight
Weight = Mass x Gravity
N = kg x N/kg
Density
DENSITY (ρ – greek letter) = mass (m) / volume (v)
Resultant Force
RESULTANT FORCE = MASS X ACCELERATION
F = m x a
Force (Springs)
FORCE = SPRING CONSTANT x EXTENSION

Of Mice and Men (1937) by John Steinbeck
Critical Success
Based on his own experiences as a ranch-hand in California during the 1920s, Of Mice and Men achieved critical acclaim.
A Novel of Protest
To what extent is Of Mice and Men a novel of protest? The novel presents a scathing social and economic criticism of American society during the Great Depression.
- Exploitation of the Weak: The story highlights the exploitation of the weak by the strong, revealing a hierarchy even among the poor and disabled
Exploring the Universe: From the Big Bang to Exoplanets
1.1 the observable universe:
It is a gap in the floating galaxies in each galaxy there are thousands of stars, planets and nebulae in the cosmos formula is 70 hydrogen, 20 helium i 5 the other elements
1.2 The dark matter:
Gas and dust of the universe subject to greater gravitational attractions qe matter we can detect. 10 xcinto galaxies in the universe, dark matter 90 remaining, i Propertys unknown composition and does not emit radiation.
3.A universe in motion, not a atonomo permance everything
Animal Behavior: Migration, Kin Selection, and Social Dynamics
Migration
- Monarch butterflies use the position of the sun as a sun compass to guide their migration.
- Polar bears are the world’s largest terrestrial carnivores, hunt seals in the winter on pack ice, and tend to lose body mass in the summer.
- The avian migrant that makes the longest non-stop flight of any land or shorebird is the bar-tailed godwit, which can fly for 3 to 8 days.
- In animals, the pacemaker is an internal clock in the brain that may regulate migratory behavior, feeding behavior, the release
Strength of Materials: Internal Forces, Simple Stress, and Analysis
1.1 Strength of Materials
The study of material resistance extends the concepts of forces from mechanics, but there’s a clear distinction between the two. Mechanics primarily focuses on the relationships between forces acting on a solid object. Statics analyzes solids at rest, while dynamics studies solids in motion, although dynamic equilibrium can be established by incorporating inertial forces. In contrast, strength of materials investigates the relationship between externally applied loads and
