Newton's Laws of Motion

Front

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

Back

kg

Front

What is the term for forces that are equal in size but opposite in direction, resulting in a net force of zero?

Back

Balanced forces

Front

Which of Newton's laws states that for every action, there is an equal and opposite reaction?

Back

Newton's 3rd Law of Motion

Front

In the context of a rocket launch, which law of motion is being demonstrated?

Back

Newton's 3rd Law of Motion

Front

What is the reaction force when a cannon fires a cannonball?

Back

The cannon moving backward

Front

Which of Newton's laws explains why a magician can pull a tablecloth out from under dishes without disturbing them?

Back

Newton's 1st Law of Motion

Front

What is inertia, and how does it relate to Newton's first law?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is a key concept in Newton's 1st Law.

Front

What does Newton's 2nd Law of Motion state about the relationship between force, mass, and acceleration?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

How does friction affect the motion of an object according to Newton's laws?

Back

Friction is a force that opposes motion, affecting the net force and thus the acceleration of an object.

Front

What is the significance of the net force in determining the motion of an object?

Back

The net force determines whether an object will accelerate, remain at rest, or move at a constant velocity.
