Newtons Law
Which of the following statements best describes Newton's First Law of Motion?
A) An object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity unless acted upon by an external force.
B) The force acting on an object is equal to the mass of the object multiplied by its acceleration.
C) Every action has an equal and opposite reaction.
D) The velocity of an object increases as the mass of the object decreases.
A) An object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity unless acted upon by an external force.

Question: Which of the following best describes Newton's Second Law of Motion?
A) The force acting on an object is equal to the mass of the object multiplied by its acceleration.
B) For every action, there is an equal and opposite reaction.
C) An object will remain at rest or in uniform motion unless acted upon by an external force.
D) The acceleration of an object is inversely proportional to the force applied.
A) The force acting on an object is equal to the mass of the object multiplied by its acceleration.
Which of the following is an example of Newton's First Law of Motion (Inertia)?
A) A rocket accelerates as it expels fuel.
B) A car speeds up when you press the accelerator.
C) A book remains at rest on a table until you push it.
D) A person feels pushed back into their seat when a car suddenly stops.
A book remains at rest on a table until you push it.
Question: Which of the following statements best describes Newton's Third Law of Motion?
A) An object at rest will remain at rest unless acted upon by an external force.
B) For every action, there is an equal and opposite reaction.
C) The force on an object is equal to its mass multiplied by its acceleration.
D) The acceleration of an object depends on its velocity and the applied force.
B) For every action, there is an equal and opposite reaction.
Which of the following statements accurately describes the relationship between force, mass, and acceleration according to Newton's Second Law?
A) If you increase mass while keeping force constant, the acceleration increases.
B) If you increase the force applied to an object, the acceleration increases.
C) Mass and acceleration are inversely related, meaning more mass results in less acceleration for a constant force.
D) If you decrease the force, the mass of the object will automatically decrease.
B) If you increase the force applied to an object, the acceleration increases.
