CH4 Motion Along a Straight Line

These flashcards contain vocabulary terms related to straight-line motion in physics, including definitions to help with understanding key concepts.

Position

The location of an object at a given time.

Velocity

The rate of change of position; speed with direction.

Acceleration

The rate of change of velocity; can be positive (speeding up) or negative (slowing down).

Displacement

The change in position of an object, measured as the difference between final and initial positions.

Average Velocity

Total displacement divided by total time taken.

Instantaneous Velocity

The velocity of an object at a specific instant in time.

Constant Acceleration

Motion where the acceleration remains the same over time.

Graphical Representation

Using graphs to visualize motion characteristics like position, velocity, and acceleration.

Free Fall

The motion of an object under the influence of gravity only, experiencing an acceleration of 9.81 m/s² downward.

Non-constant Acceleration

Acceleration that changes over time, leading to variations in velocity.
