Kinematic Equations for Motion with Constant Acceleration

Vocabulary flashcards covering the basic definitions and the first kinematic equation for straight-line motion with constant acceleration based on the lecture notes.

Constant Acceleration

A special case of motion where the acceleration at each instant is equal to the average acceleration over any time interval.

$$u$$

The initial velocity of an object at time $t = 0\,s$.

$$v$$

The final velocity of an object at time $t$.

Kinematic Equation (4.4a)

$$\text{The equation } v = u + at \text{ used to calculate velocity at all times if initial velocity and acceleration are known.}$$

Velocity-time graph (Constant Acceleration)

A graph represented by a straight line where the slope provides the value of the acceleration.

$$AO$$

The representation of the initial velocity ($u$) on the velocity-time graph in Fig. 4.19.

$$EO$$

The representation of the final velocity ($v$) at time $t$ on the velocity-time graph in Fig. 4.19.

Average Acceleration Eq. (4.3c)

The definition used to derive kinematic equations, expressed as $a = \frac{v - u}{t}$, where $t$ is the time interval.
