Question: A 50 kg object is pushed with a force of 200 N. What is the frictional force if the object moves with constant velocity? (2023)

Options:

Correct Answer: 200 N

Exam Year: 2023

Solution:

If the object moves with constant velocity, the frictional force equals the applied force, which is 200 N.

A 50 kg object is pushed with a force of 200 N. What is the frictional force if the object moves with constant velocity? (2023)

Step 1: Understand that when an object moves with constant velocity, it means that it is not speeding up or slowing down.
Step 2: Recognize that for an object to move at constant velocity, the forces acting on it must be balanced.
Step 3: Identify the applied force, which is given as 200 N (the force pushing the object).
Step 4: Since the object is moving at constant velocity, the frictional force must be equal to the applied force to keep the forces balanced.
Step 5: Therefore, the frictional force is also 200 N.

Newton's First Law of Motion – An object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.
Frictional Force – The force that opposes the motion of an object, which can be equal to the applied force when the object moves at constant velocity.
