Understanding Newton's Laws

What does Newton's First Law, also known as the law of inertia, state about an object at rest or in uniform motion?

• The object will change its motion randomly.

• The object will remain at rest or in uniform motion unless acted upon by an unbalanced force.

• The object will eventually stop due to natural forces.

• The object will accelerate without any force.

Which of the following best describes inertia?

• The tendency of an object to resist changes in its velocity.

• The rate of change of velocity of an object.

• The force applied to stop a moving object.

• The gravitational pull on an object.

Newton's Second Law of Motion can be formulated as F = ma. What does 'a' stand for in this equation?

• Area

• Acceleration

• Angular momentum

• Amplitude

According to Newton's Third Law, for every action force, there is an equal and opposite reaction force. If you push against a wall, what happens?

• The wall will push back with a different force.

• The wall will not push back.

• The wall will push back with the same force.

• The wall will move in the direction of the force.

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

• Newton

• Joule

• Pascal

• Watt

If the mass of an object is constant, how is acceleration related to the net force applied to it?

• Acceleration is inversely proportional to the net force.

• Acceleration is not related to the net force.

• Acceleration is directly proportional to the net force.

• Acceleration decreases as the net force increases.

What does mass measure in terms of inertia?

• The resistance of an object to change in its state of motion.

• The weight of an object.

• The volume of an object.

• The speed of an object.

Which of the following scenarios is an example of Newton's First Law in action?

• A car coming to a stop at a red light.

• A ball rolling uphill and eventually stopping.

• A book remaining at rest on a table.

• A rocket launching into space.

If you double the mass of an object while applying the same force, what happens to the acceleration?

• It doubles.

• It remains the same.

• It is halved.

• It quadruples.

When a hammer strikes a nail and drives it into a piece of wood, which of Newton's laws best describes the interaction between the hammer and the nail?

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• None of the above
