Multiple Choice

An object is moving in a circle at a constant speed of 10 m s-1. 

We say that it has a constant speed but its velocity is changing. Why?

Un objeto se mueve en círculo con una rapidez constante de 10 m s-1.

Decimos que tiene una rapidez constante pero su velocidad está cambiando. ¿Por qué?

• The velocity is changing because the object is slowing down as it moves in a circle.
• The velocity is changing because the object is speeding up as it moves in a circle.
• The velocity is changing because the object is not moving at a constant speed in a circle.
• The velocity is changing because the direction of the object is constantly changing as it moves in a circle.
