Newton's Three Laws

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as F=ma.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

Define inertia in the context of Newton's First Law.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force.

Front

Provide an example of Newton's First Law in everyday life.

Back

A soccer ball remains at rest until a player kicks it.

Front

What does the equation F=ma represent?

Back

It represents Newton's Second Law, where F is the net force, m is the mass, and a is the acceleration.

Front

Explain the concept of action-reaction pairs in Newton's Third Law.

Back

When one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.

Front

What is the significance of the net force in Newton's Second Law?

Back

The net force determines the acceleration of an object; it is the vector sum of all forces acting on the object.

Front

How does Newton's First Law relate to seatbelts in cars?

Back

Seatbelts provide the necessary force to stop passengers from continuing forward due to inertia during sudden stops.
