Study Notes
Physics Concepts
- Newton’s Second Law: An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net force.
- Impulse-Momentum Theorem: This theorem states that the change in momentum of an object is equal to the impulse applied to it.
Forces
- Balanced Forces: Occur when the net force on an object is zero, resulting in no change in its motion.
- Unbalanced Forces: Occur when the net force on an object is not zero, causing a change in its motion.
- Conservative Forces: A force that does not depend on the path taken, only the initial and final positions.
- Applied Force: A force applied to an object by another object.
- Frictional Force: A force that opposes motion between two surfaces in contact.
- Normal Force: A force exerted by a surface that prevents an object from passing through it.
Motion
- Projectile Motion: The motion of an object that is thrown or projected into the air.
- Free-Fall: The motion of an object that is only influenced by gravity.
- Velocity: The rate of change of an object's position, including both speed and direction.
- Impact Velocity: The velocity of an object just before it collides with another object.
- Displacement: The change in position of an object.
Energy
- Kinetic Energy: The energy of a moving object.
- Potential Energy: The energy of an object due to its position or configuration.
Units and Conversions
- SI Units: An internationally recognized system of units.
- Scientific Notation: A way of representing very large or very small numbers using exponents.
Graphs
- Pie Chart: A type of graph that shows the proportion of a whole that each part represents.
- Scatter Plot: A type of graph that shows the relationship between two variables.
- Histogram: A type of graph that shows the distribution of data.
- Time Series: A type of graph that shows data over time.
Cartesian coordinate system
- Quadrant I: x>0, y>0
- Quandrant II: x<0, y>0
- Quadrant III: x<0, y<0
- Quadrant IV: x>0, y<0
Center of mass
- Located at the point where the object's mass is evenly distributed.
Titanic example
- The Titanic's speed was 14,444.44 m/s
- The momenta of the ship was 498,622,061.8 kg.m/s
- The momenta of the iceberg was 1 kg.m/s assuming the iceberg completely stopped and crumbled after impact.
- The velocity of the ship after the collision would still be 14,444.44 m/s.
