Motion in One Dimension

Flashcards covering key concepts and definitions related to motion in one dimension.

Kinematics

Describes motion while ignoring the agents that caused the motion.

Displacement

Defined as the change in position during some time interval, represented as Δx = x2 - x1.

Position-Time Graph

Shows the motion of a particle, with the smooth curve representing the motion between data points.

Average Velocity

Rate at which displacement occurs, calculated as x/t, with SI units of m/s.

Instantaneous Velocity

The limit of the average velocity as the time interval approaches zero, indicating what is happening at every point of time.

Scalar vs Vector

Vector quantities require both magnitude and direction; scalar quantities are described by magnitude only.

Acceleration

The rate of change of velocity, with SI units of m/s².

Free Fall

An object moving freely under the influence of gravity alone, irrespective of its initial motion.

g (acceleration due to gravity)

The magnitude of free fall acceleration, approximately 9.80 m/s² at Earth's surface.

Kinematic Equations

Equations that can be used with any particle under uniform acceleration, used to solve problems involving one-dimensional motion.
