Newton's Laws of Motion Flashcard

Front

What are Newton's Laws of Motion?

Back

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

Front

What is the first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion 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 is the 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 (F=ma).

Front

What is the third law of motion?

Back

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

Front

What is thrust in the context of rocket propulsion?

Back

The force produced by the expulsion of gas from a rocket engine, propelling the rocket forward.

Front

What role does gravity play in rocket launches?

Back

Gravity is the force that pulls the rocket towards the Earth, which must be overcome for the rocket to ascend.

Front

What is drag?

Back

The resistance force that opposes the motion of an object through a fluid (like air).

Front

What is lift?

Back

The force that directly opposes the weight of an object and holds it in the air, crucial for flight.

Front

How does mass affect acceleration according to Newton's second law?

Back

A greater mass results in less acceleration for the same amount of force applied.
