T It takes a force to change the momentum of an object. How can we change momentum?
T Changing the momentum of an object could be by changing its speed or its direction.

W Unbalanced forces are needed to cause objects to: - stop or start moving, - change their speed, - direction of motion These are all forms of acceleration (qualitative only). Why do we need unbalanced forces?
W The acceleration is in the direction of resultant force and the speed of the change is dependent on the size of the force. What is acceleration dependent on?
