Question

*If frictional force is not acting on a moving object, what will be the next effect on that object?*

1️⃣ The object stops
2️⃣ The object continues to move at the same speed
3️⃣ The speed of the object increases
4️⃣ There will be no effect​

Answer 1

Step-by-step explanation:

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.Friction oppose relative motion. In its absence, a moving object will not stop.

Answer (B) the object will keep moving

Answer 2

If frictional force is not acting on a moving object then (2) the object continues to move at the same speed.

• According to Newton's second law of motion, An object in motion stays in motion and an object at rest stays at rest until and unless an external force is applied.
• We consider this situation to be in a vacuum, so in the given situation there are no external forces on the object except the frictional force.
• Now if the object is in motion and the frictional force is no anymore acting upon the body then the object will continue in motion until some force stops it.
• As the friction force was stopping the motion of the object, if it would have continued to act then the object would have come to rest.
