Which of the following statements are true about the motion of an object?

A force perpendicular to the momentum changes the direction of the momentum but not its magnitude.

To change the magnitude of the momentum you need to apply a force parallel to the momentum (either in the same direction as the momentum or the opposite direction).

To make an object turn to the left, something has to exert a force to the right on the object.

When an object moves at constant speed along a curving path, the net force on the object must act straight outward from the center of the kissing circle.
