Question

Use the slider to apply a force of about 400 N. After 2 s have elapsed in the simulation, decrease the Applied Force (force exerted) slowly back to zero. Try to do this adjustment in roughly 2 s . While the Applied Force (force exerted) is decreasing, the velocity is:______.

a. constant.
b. increasing.
c. decreasing.

Answer 1

While decreasing the force exerted back to zero, the object's velocity is decreasing because the applied force which causes acceleration is reduced, leading to a reduction in velocity.

Step-by-step explanation:

When you apply a force of about 400 N and then after 2 seconds you start decreasing the applied force slowly back to zero over roughly 2 seconds, the velocity is decreasing. This is because the force exerted on the object is responsible for changes in velocity, which is a result of acceleration. When the force begins to decrease, so does the acceleration, which means the velocity will also start to decrease.
