FE 1.3 ACCELERATION QUIZ REVIEW

If a train is slowing down, it is accelerating.

Si un tren está disminuyendo la velocidad, está acelerando.

• Maybe

• False

• True

To find the ACCELERATION of an object moving in a straight line, you must calculate the change in DISTANCE divided by time.

Para encontrar la aceleración de un objeto que se mueve en línea recta, debe calcular el cambio en la distancia dividido por el tiempo.

• True- distance

• False-velocity

• False-mass

A Merry-Go-Round turning at a constant speed of 4 m/s is NOT accelerating. 

Un tiovivo girando a una velocidad constante de 4 m/s no está acelerando.

• False, it is accelerating due to change in direction.

• True, it is not accelerating.

• False, it it has positive acceleration.
