Physics please answer thank you and explain Sec 6 Direction of Acceleration What determines the direction of the acceleration vector (assuming the acceleration is not zero)? The velocity vector. The friction force. The net force. A "pulling force" (e.g. a tension in a string, a push, or a motor). 67 Ismo! For the incorrect options, explain why this option is incorrect. For example you could describe a counter example.
