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:

I think that you would perceive the component of the force along the line of motion to be moving forward. I think that this component is in the direction of motion.

#$&*

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

answer/question/discussion:

I think that the object will speed up.

#$&*

• 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 right.

#$&*T

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

answer/question/discussion:

The object will veer 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:

The component perpendicular to the line of motion.
