Question: If a force of 15 N is applied to a 3 kg object, what is the net force acting on the object if it is already moving with a velocity of 5 m/s? (2022)

Options:

  1. 15 N
  2. 3 N
  3. 0 N
  4. 18 N

Correct Answer: 15 N

Exam Year: 2022

Solution: 

The net force is still 15 N as it does not depend on the velocity of the object.

Questions & Step-by-Step Solutions

If a force of 15 N is applied to a 3 kg object, what is the net force acting on the object if it is already moving with a velocity of 5 m/s? (2022)
  • Step 1: Understand that a force of 15 N is being applied to the object.
  • Step 2: Recognize that the object has a mass of 3 kg and is already moving.
  • Step 3: Note that the net force acting on an object is the total force applied to it.
  • Step 4: Realize that the net force does not depend on the object's current velocity.
  • Step 5: Conclude that since a force of 15 N is applied, the net force is 15 N.
  • Net Force – The net force acting on an object is the vector sum of all forces acting on it, regardless of its velocity.
  • Newton's Second Law – The net force is related to mass and acceleration (F = ma), and is independent of the object's current velocity.
