Object Moving Right: Force & Speed Variations

[zachmac5]

An object is moving to the right, and experiencing a net force that is directed to the right. The magnitude of the force is decreasing with time. The speed of the object is:

A) Increasing
B) Constant in time
C) Decreasing

What does a force cause?
Does the direction of the force ever change?

I would first clarify that the object is experiencing a net force that is directed to the right, meaning there are no other forces acting on it that could change its direction of motion. With this information, I can confidently say that the speed of the object is decreasing.

This is because the net force is decreasing with time, meaning that the overall force acting on the object is getting weaker. According to Newton's Second Law of Motion, force is directly proportional to acceleration. Therefore, as the force decreases, the acceleration of the object also decreases. This results in a decrease in the object's speed over time.

It is important to note that the direction of the object's motion is not affected by the decreasing force. The object will continue to move to the right, but at a slower speed.

In summary, the correct answer is C) Decreasing. This is due to the decreasing net force causing a decrease in acceleration and therefore a decrease in speed over time.
