Study Notes
Graphing Basics
- Position is plotted on the y-axis while time is on the x-axis.
- In velocity vs. time graphs, the initial velocity (vo) is the y-intercept.
- The slope of a velocity vs. time graph represents acceleration.
Slope and Calculations
- To calculate the slope of a position vs. time graph, use two data points; for example, points (1.0s, 5.2m) and (3.7s, 6.4m) yield a slope of 0.44 m/s.
- Manual measurements require recording significant figures, where the last digit is an estimate of precision based on the measuring instrument used.
SI Units
- The standard SI units are kilograms for mass, meters for length, and seconds for time.
Measurement Tools
- Common measuring devices include metric rulers, micrometers, vernier calipers, and laboratory balances.
Motion Concepts
- Uniform acceleration means a mass experiences constant acceleration in a straight line.
- Main graphs in kinematics are acceleration vs. time, velocity vs. time, and position vs. time.
Kinematic Equations
- The equation v = vo + at describes the relationship in velocity vs. time graphs.
Projectile Motion
- In projectile motion, the x-component of velocity remains constant throughout the motion.
- For a projectile, the overall velocity is minimized at maximum height.
- Maximum range for projectile firing occurs at a 45-degree angle.
Energy Principles
- The Law of Conservation of Mechanical Energy states that total mechanical energy in a system is conserved without non-conservative forces.
- The SI unit for energy is the joule.
Projectile Height and Flight Time
- The maximum height determination involves subtracting the launch height from the measured height.
- Time of flight for a projectile is dependent on its initial height.
Circular Motion
- Centripetal force induces circular motion, often a combination of gravity and tension.
- Centripetal force is inversely proportional to the radius of the circular path and directly proportional to the square of the tangential velocity.
- Newton's First Law indicates that a net force is needed for a change in an object's state of motion.
Forces and Acceleration
- The net force equation is F = (M2 - M1)g.
- The theoretical acceleration equation is a = F / (M2 + M1).
- In a net force vs. acceleration graph, the slope represents mass.
