Chapter 2 Motion in One Dimension Flashcards

Flashcards covering key vocabulary and concepts from Chapter 2: Motion in One Dimension.

Uniform Motion

Motion where successive images of a rider are the same distance apart, indicating constant velocity.

Acceleration

A rapid change in speed.

Free Fall

Motion determined by gravity alone.

Motion Diagram

Marking the position of an object at successive times to analyze motion.

Representing Position

Using an x-axis to analyze horizontal motion and motion on a ramp, with the positive end to the right, and a y-axis for vertical motion, with the positive end up.

Position-versus-time graph

On a position-versus-time graph, a faster speed corresponds to a steeper slope.

Uniform Motion or Constant-Velocity Motion

Straight-line motion in which equal displacements occur during any successive equal-time intervals.

Instantaneous Velocity

An object’s velocity—a speed and a direction—at a specific instant of time t.

Acceleration

The ratio of the change in velocity to the change in time.

Free Fall

Motion where the free-fall acceleration always points down, and no other forces are in effect.

Problem-Solving Approach

A four step method that breaks down problem solving into smaller steps consisting of Strategize, Prepare, Solve, and Assess.
