Dynamics Basic Quiz

Which of Newton's Laws states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force?

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• None of the above

What is the formula for calculating force according to Newton's Second Law of Motion?

Newton's Third Law states that for every action, there is:

• An equal and opposite reaction

• A reaction in the same direction

• No reaction

• A double reaction in the opposite direction

What is the unit of force in the International System of Units (SI)?

• Newton (N)

• Joule (J)

• Kilogram meter per second (kg m/s)

If the mass of an object is doubled while its force remains constant, what happens to its acceleration?

• It remains the same

• It is halved

• It is doubled

• It is quadrupled

According to Newton's Second Law, if the net force acting on an object is tripled while the mass remains constant, what happens to the acceleration?

• It remains the same

• It is halved

• It is doubled

• It is tripled

What does it mean when we say a force is "balanced"?

• The force causes acceleration

• The force causes an object to move at constant velocity

• The net force acting on an object is zero

• The force is only acting in one direction
