Unit 2: Newton's Laws of Motion

Front

What are Newton's Laws of Motion?

Back

Three fundamental principles that describe the relationship between the motion of an object and the forces acting on it.

Front

What does Newton's First Law of Motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What does Newton's Second Law of Motion describe?

Back

The relationship between force, mass, and acceleration, expressed as F = ma.

Front

What is the formula for calculating force?

Back

Force (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 an example of Newton's First Law in everyday life?

Back

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

Front

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

Back

Mass is a measure of an object's resistance to acceleration when a force is applied.

Front

What is a reaction force in Newton's Third Law?

Back

The force exerted by an object in response to an action force.

Front

How does gravity relate to Newton's Laws?

Back

Gravity is a force that acts on all objects with mass, influencing their motion according to Newton's laws.
