Kinematics in One Dimension - Chapter 2

A set of vocabulary flashcards covering key terms and definitions related to Kinematics in one dimension as discussed in Chapter 2.

Reference Frame

A perspective from which motion is measured, affecting the observed speed and position of an object.

Displacement

The vector quantity that represents the change in position of an object, measured from its starting point.

Distance

The scalar quantity representing the total path length an object travels, regardless of direction.

Average Velocity

The total displacement divided by the total time taken, incorporating direction.

Instantaneous Velocity

The velocity of an object at a specific moment in time, found by taking the limit of average velocity as the time interval approaches zero.

Acceleration

The rate of change of velocity over time, which can be positive or negative.

Deceleration

A decrease in velocity, occurring when acceleration acts in the direction opposite to the velocity.

Constant Acceleration

When the rate of acceleration remains unchanged over a period of time.

Freely Falling Objects

Objects that are falling under the influence of gravity alone, experiencing constant acceleration.

Acceleration due to Gravity

The acceleration that is imparted to objects due to Earth's gravitational pull, approximately 9.80 m/s².

Graphical Analysis of Motion

The method of using graphs to represent motion, showing relationships between distance, time, and velocity.

Average Acceleration

The change in velocity divided by the time interval during which the change occurs.
