Question

indicate the reasons why the centripetal acceleration (and centripetal force) always point to the center in uniform circular motion. select all that apply.
□ ( f = m a ), and since \m\ points toward the center, so does f.
□ ( overrightarrow { a } = \frac { delta overrightarrow { v } } { delta t } ), and the ( delta t ) points toward the center of the circle.
□ ( f = m a ), and since \a\ points toward the center, so does f.
□ ( overrightarrow { a } = \frac { delta overrightarrow { v } } { delta t } ), and the ( delta v ) points toward the center of the circle.

Explanation:

Brief Explanations
  • La ecuación \(F = ma\) muestra que la fuerza (\(F\)) y la aceleración (\(a\)) son vectores paralelos. Si la aceleración centrípeta (\(a\)) apunta hacia el centro, entonces la fuerza centrípeta (\(F\)) también apunta hacia el centro.
  • La aceleración se define como \(\vec{a}=\frac{\Delta\vec{v}}{\Delta t}\). En el movimiento circular uniforme, el cambio en la velocidad (\(\Delta\vec{v}\)) apunta hacia el centro del círculo.

Answer:

  • \(F = ma\), and since "a" points toward the center, so does \(F\).
  • \(\vec{a}=\frac{\Delta\vec{v}}{\Delta t}\), and the \(\Delta v\) points toward the center of the circle.
