Questions & Step-by-Step Solutions
A 50 kg object is moving with a constant velocity. What can be said about the net force acting on it?
Correct Answer: Net force is zero.
Step 1: Understand what constant velocity means. It means the object is moving at the same speed and in the same direction.
Step 2: Recall Newton's First Law of Motion. It states that an object will remain at rest or in uniform motion unless acted upon by a net external force.
Step 3: Since the object is moving with constant velocity, it is not speeding up, slowing down, or changing direction.
Step 4: Therefore, there is no net external force acting on the object. The forces acting on it are balanced.
Step 5: Conclude that the net force acting on the object is zero.
Newton's First Law of Motion – An object in motion stays in motion with the same velocity unless acted upon by a net external force.
