Rate of change of momentum of a body is a result of the _____ acting on that body.

The correct answer is Net Force.

Key Points

• Newton's Second Law of Motion states that the rate of change of momentum of a body is directly proportional to the net force acting on it.
• The formula representing this law is F = ma, where F is the net force, m is the mass, and a is the acceleration.
• Momentum is a vector quantity, which means it has both magnitude and direction.
• Net force is the vector sum of all the forces acting on a body. If multiple forces are acting, they must be combined vectorially to find the net force.
