Question

Which one(s) of the following force diagrams depict an object moving to the right with a constant speed? Which one(s) of the force disarms depict an object moving to the left with a constant speed?

Answer 1

Answer:

diagram D and A respectively

Explanation:

In diagram d aa arrow line is shown moving constantly towards right and it is moving with a constant speed of 20

similarly in diagram b it is shown that a object represented by line arrow is moving in left direction with a constant speed of 20 ..

Answer 2

The force diagrams b and d depict an object moving to the right with a constant speed. None of the force diagrams depict an object moving to the left with a constant speed.

• In the force diagram a, the force on the left and the right side is the same. Also, the force on the front and the back are the same. So the object is stationary since the net force becomes zero.
• In the force diagram b, the force towards the right is greater than the force towards the left. So the object moves towards the right.

• In the force diagram c, no force is applied towards the left or right. The force applied at the front and the back are the same. Hence, the object is at rest since the net force is zero.

• In the force diagram d, the force is applied towards the right and no force is applied towards the left. So the object moves towards the right.
