Question

A body falls down with a uniform velocity. What do you know about the force acting. on it?

• A. No force acts on it
• B. Balanced forces are acting on it
• C. Unbalanced forces are acting on it
• D. The acceleration is negative

Answer 1

Answer:

B. Balanced forces are acting on it

• The correct answer is indeed Balanced forces are acting on it.

• When a body falls down with a uniform velocity, it means that its acceleration is zero.

• According to Newton's First Law of Motion, an object at rest or moving with a uniform velocity will remain in that state unless acted upon by an external force.

• Since the body is falling with a uniform velocity, the net force acting on it must be zero. This means that the forces acting on the body are balanced, and there is no net force causing it to accelerate.

In this case, the two balanced forces are:

1. Weight (or gravity): pulling the body downwards

2. Upward force (such as air resistance or buoyancy): opposing the weight and keeping the body falling at a uniform velocity

So, to confirm:

• The correct answer is indeed Balanced forces are acting on it.
