22 Questions
According to Newton's First Law of Motion, what will happen to a body at rest when no external force acts upon it?
It will remain at rest.
What is the condition for an object to be in dynamic equilibrium?
Acted upon by balanced forces.
In Newton's Second Law of Motion, what is the relationship between acceleration and the net force acting on a body?
Acceleration is directly proportional to the net force.
What type of equilibrium occurs when an object is at rest and acted upon by balanced forces?
Static equilibrium
What does Newton's Third Law of Motion state about action and reaction?
Action and reaction forces are always equal in magnitude and opposite in direction.
Which law of motion describes the scenario where a body in uniform motion continues moving at that speed unless acted upon by an external force?
Newton's First Law
