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.
