Newton's 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 an unbalanced force.

Front

What is the formula to calculate force according to Newton's Second Law?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What does Newton's Third Law of Motion state?

Back

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

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.

Front

What is an example of Newton's First Law in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops, demonstrating inertia.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

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

Back

The unit of force is the Newton (N).

Front

What is an example of Newton's Third Law in action?

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

What is the significance of balanced forces?

Back

Balanced forces result in no change in motion; the object remains at rest or continues to move at a constant velocity.
