When a force acts on an object from an angle other than either 0° or 180° to the direction of motion:

1) The force is perpendicular to the direction of motion, so no work gets done.

2) The parallel and perpendicular component of the force both do work.

3) The perpendicular vector component of the force does work but the parallel one does not.

4) The parallel vector component of the force does work but the perpendicular one does not.

5) The force is not in the direction of motion, so no work gets done.

The answer is #4. I had that same question and got it right.

The correct statement is:

2) The parallel and perpendicular component of the force both do work.

When a force acts on an object from an angle other than 0° or 180° to the direction of motion, the force can be divided into two components: the parallel component and the perpendicular component. The parallel component of the force is in the same direction as the object's motion, while the perpendicular component is at a right angle to the motion.

Both the parallel and perpendicular components of the force contribute to the work done on the object. The parallel component of the force works to change the object's speed or direction of motion, while the perpendicular component of the force works to change the object's position or shape.

Therefore, statement 2) is correct: "The parallel and perpendicular component of the force both do work."

The correct answer is 2) The parallel and perpendicular component of the force both do work.

When a force acts on an object at an angle other than 0° or 180° to the direction of motion, it can be split into two components: the parallel component and the perpendicular component with respect to the direction of motion.

The parallel component of the force acts in the same direction as the object's motion. This means that it contributes to the object's displacement and does work. The work done by the parallel component can be calculated using the formula: work = force * displacement * cos(angle). Here, the angle is the angle between the force vector and the displacement vector.

The perpendicular component of the force acts perpendicular to the direction of motion. Since it is perpendicular, it does not contribute to the object's displacement. However, it does exert a force on the object, causing it to change direction. Although the perpendicular component does not do work in terms of contributing to the object's displacement, it does do work in changing the object's direction or causing it to move in a curved path.

To get the answer, one needs to understand the concept of work and how it is related to the components of a force. Additionally, knowledge of trigonometry is necessary to calculate the work done by the parallel component of the force using the formula mentioned above.
