Answer 2

The force is changed by changing tension in pulley system

Explanation:

• A pully with one wheel allows you to reverse the direction of your lifting force by pulling down on a rope(that's looped over the wheel), lifting your weight.
• With a two-wheel pulley, you reduce the effort you exert to lift the same amount of weight.
• You lift the weight with half the force.
• Tension will pull to the right in the direction of the pulley clockwise.
• Object two, which is the hanging mass to the right of the pulley, will have the tension pulling up counterclockwise and the force of gravity pulling down clockwise.
• Apply Newton's second law of motion for object one to the left of the pulley.
• A pulley serves to change the direction of a tension force, and may also(in the case of multiple-pulley system)change its magnitude.
• The tension of an "ideal cord" that runs through an "ideal pulley" is the same on both sides of the pulley(and at all points along the cord).
