Flashcards: One-Dimensional Motion Fundamentals — 10 cartões

Position — definition?

Location relative to a reference point.

Displacement — definition?

Change in position; vector quantity.

Displacement — difference?

Change in position, includes direction.

Distance vs displacement — difference?

Distance: total path; Displacement: net change.

Velocity — formula?

Displacement over time, Δx/Δt.

Average velocity — formula?

Δx divided by Δt; vector.

Instantaneous velocity — definition?

Derivative of position: dx/dt.

Equations of motion — for constant acceleration?

v = v_i + at; x = x_i + v_i t + ½ at²; v² = v_i² + 2a(x - x_i).

Gravity — acceleration during free fall?

a = -9.80 m/s² downward.

Projectile motion — independence of components?

Horizontal constant, vertical affected by gravity.
