Physics Concepts: Motion and Acceleration

Vocational flashcards covering key concepts in motion and acceleration from physics lecture notes.

Average Acceleration

The change in velocity over time, expressed as a_m = \frac{\Delta v}{\Delta t}, measured in m/s².

Uniformly Accelerated Rectilinear Motion

Motion with constant acceleration along a straight trajectory, represented by specific laws of motion.

Motion Equations

Described by equations such as S = S_0 + V_0t + \frac{1}{2}at^2 for position and V = V_0 + at for velocity.

Free Fall

The motion of an object under the influence of gravity alone, with acceleration g = 9.8 m/s².

Vertical Launch

The upward motion of an object where the influence of air resistance is negligible, governed by the equation v = V_0 - gt.

Average Velocity

The ratio of displacement to time interval, calculated as V_m = \frac{S_2 - S_1}{\Delta t}, measured in m/s.

Space-Time Graphs

Graphs that depict the position of an object versus time, showing linearity for constant velocity and a curve for accelerated motion.

Instantaneous Velocity

The velocity of an object at a specific moment in time, determined using the slope of the tangent line on a space-time graph.

Constant Velocity Motion

Motion where an object travels with a fixed speed along a straight path, described by the equation S = S_0 + vt.

Secant and Tangent Lines

A secant line represents average velocity over an interval, while a tangent line represents instantaneous velocity at a specific point.
