Seed question 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 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:
The component of the force in the direction of motion is forward.
The component is opposite the direction 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:
perpendicular
