1. Describe a situation where the block moves as the force is applied to it, yet the force does no work over a non-zero time interval. How can this be?

2. Set the initial position of the block to zero, and set the initial velocity to —3 m/s. Run the simulation. When is the work negative? When is it positive? Why?

3. Since the force is constant, what can you say about the acceleration of the block?

4. How can you maximize the final velocity of the block? Can you do the same amount of work and have the block moving more slowly?

5. Create a graph to represent the force (y-axis) and the position (x-axis).

6. What is the area under the curve of this graph?

1. We know that Force= Work. Displacement.

So, if net displacement of any box is 0, then in that case the work done by force is equal to 0.

Eg- Moving a Box in complete circle, where the starting and ending point is same. In this case, displacement is 0. So is Work Done.
