Explain why an object moving around a circle is said to be accelerating when it has no resultant force acting upon it.
If an object has no resultant force acting upon it then it is moving at a constant speed. Acceleration is a vector quantity meaning that it includes magnitude and direction. When it is moving around a circle the direction in which an object is moving is continuously changing; therefore, the object is constantly accelerating.
