An object moving in the direction 120 degrees (as measured counterclockwise to the positive x axis) encounters a net force whose direction is 270 degrees.
Sketch the force and its component in the direction of motion, as well as its component perpendicular to the direction of motion.
answer/question/discussion:
Suppose you are facing in the direction of motion. Do you perceive the component of the force in the direction of motion to be forward or backward? It this component in the direction of motion or opposite to the direction of motion?
answer/question/discussion:
Backwards, opposite of motion
Will the object speed up, slow down or maintain a constant speed?
answer/question/discussion:
slow down
If you are facing in the direction of motion, then the directions perpendicular to the direction of motion will be to your right and to your left. Is the component of the force perpendicular to the direction of motion to the right or to the left?
answer/question/discussion:
to the right
Will the veer to the right, to the left or maintain straight-line motion?
answer/question/discussion:
to the right
Which is greater in magnitude, the component of the force along the line of motion or the component perpendicular to the line of motion?
answer/question/discussion:
component perpindicular to the line of force.
300 deg is directly opposite the motion, while 210 deg and 30 deg are perpendicular.
270 deg is closer to 300 deg than to either 210 deg or 30 deg, so the parallel component is greater in magnitude than the perpendicular.
