Physics Introduction
- Physics is the study of natural phenomena, focusing on the fundamental laws and principles governing the behavior of the physical universe.
Standards of Measurement
- Length: measured in units such as meters (m), centimeters (cm), and kilometers (km).
- Mass: measured in units such as kilograms (kg), grams (g), and milligrams (mg).
- Time: measured in units such as seconds (s), minutes (min), and hours (h).
Units and Order of Magnitudes
- Scientific notation is used to express very large or very small numbers.
- Order of magnitude is the power of 10 that a quantity is closest to.
Dimensional Analysis
- Involves checking the units of a physical quantity to ensure they are consistent.
- Used to convert between different units and to identify errors in calculations.
Measurement Uncertainty
- The uncertainty of a measurement is the range of values within which the true value is likely to lie.
- It is a measure of the accuracy of a measurement.
Significant Figures
- The number of significant figures in a measurement indicates the degree of precision.
- Rules exist for determining the number of significant figures in a calculation.
Motion in One Dimension
- Describes motion in a straight line, using concepts such as displacement, velocity, and acceleration.
- Equations of motion describe the relationship between these quantities.
Vectors and Cartesian Coordinate System
- Vectors are used to represent quantities with both magnitude and direction.
- The Cartesian coordinate system is used to describe the location of objects in space.
Kinematic Equations
- Describe the motion of an object in terms of its position, velocity, and acceleration.
- Four kinematic equations exist, relating these quantities to time.
Graphical Analysis of Motion
- Graphs are used to visualize and analyze motion, including position-time, velocity-time, and acceleration-time graphs.
- Graphs can be used to identify patterns and relationships in motion.
Projectile Motion
- Describes the motion of an object under the influence of gravity, such as a thrown ball or fired projectile.
- The trajectory of a projectile is a parabola.
Relative Velocity and Acceleration
- The velocity and acceleration of an object can be relative to another object or a reference frame.
- Relative velocity and acceleration are used to describe motion in different reference frames.
Uniform Circular Motion
- Describes the motion of an object in a circular path, at a constant speed.
- Centripetal force and acceleration are necessary for uniform circular motion.
Newton's Laws of Motion
- Three laws describe the relationship between a body and the forces acting upon it.
- The laws describe the motion of an object, including the law of inertia, the law of acceleration, and the law of reciprocal actions.
Forces of Friction
- Frictional forces oppose motion, and exist between surfaces in contact.
- There are different types of friction, including static, kinetic, and rolling friction.
Work and Energy
- Work is done when a force is applied to an object, causing it to move.
- Energy is the ability to do work, and is measured in units such as joules (J).
Conservation of Energy
- The total energy of a closed system remains constant, but may change form.
- The law of conservation of energy applies to all types of energy, including kinetic, potential, and thermal energy.
Linear Momentum
- The product of an object's mass and velocity.
- Linear momentum is conserved in closed systems, and is a measure of an object's tendency to continue moving.
Center of Mass and Translational Motion
- The center of mass is the point at which the entire mass of an object can be considered to be concentrated.
- The center of mass is used to describe the motion of an object, including its translational motion.
Rotational Motion
- Describes the motion of an object rotating around a fixed axis.
- Rotational kinematics and dynamics describe the motion and forces involved in rotational motion.
Angular Momentum
- A measure of an object's tendency to continue rotating.
- Angular momentum is conserved in closed systems, and is a measure of the rotational motion of an object.
Thermodynamics
- The study of heat, temperature, and energy transfer.
- Laws of thermodynamics describe the behavior of energy and its interactions with matter.
Heat and Internal Energy
- Heat is the transfer of energy from one body to another due to a temperature difference.
- Internal energy is the total energy of an object, including its kinetic energy, potential energy, and thermal energy.
