Question

If no external force acts on a moving object:

a)
It will not be affected at all.
b)
It should remain in motion But, it will stop due to Friction
c)
It will stop moving.
d)
It will remain at rest forever.

Correct answer is option 'B'. Can you explain this answer?

Answer

No external force is being applied on that moving object. If no force is applied then it will continue doing it's work. Just like in the question they have asked, it was moving in a straight line, so no external force is applied that's why it is moving in the same sped in a straight line.

Answer

Due to the inertia of a body ,it will be in motion with the same speed unroll any external force is applied to it

Answer

If an object is moving at a constant speed or velocity, it will continue at that speedunless acted upon by some force along the line of motion. If an object is moving, itwill move in a straight line unless acted upon at an angle by some force.

Answer

Since the object is moving then if there is no external force applied on it then it means it has no any mean(force applied to object) to come in rest. So, the object keep moving....also due to Inertia of Motion

Answer

If no force is applied to a moving object, it should remain in motion as per the first law of motion. But, it is stopped due to friction.

Answer

Introduction:
When no external force acts on a moving object, its motion is determined by the forces acting on it. In this scenario, the only force that opposes the motion of the object is friction. This frictional force eventually brings the object to a stop.

Explanation:

1. Inertia:
When no external force acts on a moving object, it continues to move due to its inertia. Inertia is the tendency of an object to resist changes in its motion. According to Newton's first law of motion, an object in motion will remain in motion with the same speed and direction unless acted upon by an external force.

2. Friction:
Friction is a force that opposes the motion of an object when it is in contact with a surface. When a moving object encounters friction, it experiences a force that acts in the opposite direction to its motion. This force gradually slows down the object and eventually brings it to a stop.

3. Effect of Friction:
Friction acts as a retarding force on the moving object. As the object continues to move, the frictional force opposes its motion and reduces its speed. The magnitude of the frictional force depends on the nature of the surfaces in contact and the force pressing them together.

4. Balancing Forces:
In the absence of any external force, the only force acting on the moving object is friction. Initially, the force of friction balances the inertia of the object, allowing it to maintain its motion. However, as the object moves, the frictional force gradually overcomes the inertia and slows down the object.

5. Stopping Motion:
Due to the continuous action of friction, the object's speed decreases until it eventually comes to a stop. At this point, the force of friction is equal in magnitude and opposite in direction to the object's motion, resulting in a net force of zero.

Conclusion:
In the absence of any external force, a moving object will eventually stop due to the frictional force acting on it. This is because the frictional force gradually overcomes the object's inertia, reducing its speed until it comes to a rest. Therefore, option B, 'It should remain in motion, but it will stop due to friction,' is the correct answer.

Answer

Yes due to their inertia

Answer

I believe that this is incorrect because the object may be at rest too.

A

nd if no external force is applied it will not be affected at all.
Therefore, the correct option should be 'A'.
