SEED 19.3

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 along the line of motion, as well as its component perpendicular to the line of motion.

answer/question/discussion:

Suppose you are facing in the direction of motion. Do you perceive the component of the force along the line 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: Forward, it is the direction of motion.

Will the object speed up, slow down or maintain a constant speed?

answer/question/discussion: More than likely speed up because there was force applied to it

If you are facing in the direction of motion, then the line perpendicular to the direction of motion will run to your right and to your left. Is the

component of the force perpendicular to the line of motion directed to the right or to the left?

answer/question/discussion: To the left

Will the object veer to the right, to the left or maintain straight-line motion?

answer/question/discussion: Veer to the left

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: The component perpendicular

The component parallel to the direction of motion opposes motion. See the link below; no need to submit a revision of you understand.
