Rocket Science: 2nd Nine Weeks

Front

What is Newton's 1st 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 does Newton's 1st Law of Motion explain about coffee spilling when a car stops quickly?

Back

It explains that the coffee continues to move forward due to inertia when the car stops.

Front

Who is known for improving the efficiency of rocket engines from 2% to 64% in 1926?

Back

Robert Goddard.

Front

What is 'Drag' in the context of rocket science?

Back

Drag is the force that opposes an object's motion through the air, also known as air resistance.

Front

Which law of motion explains how rockets gain lift?

Back

Newton's 3rd Law of Motion.

Front

What is Newton's 2nd 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.

Front

How does Newton's 2nd Law relate to rocket propulsion?

Back

It explains that the greater the force applied to the rocket, the greater its acceleration will be.

Front

What is the formula for Newton's 2nd Law?

Back

F = ma (Force equals mass times acceleration).

Front

What is inertia?

Back

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

Front

What is the significance of Robert Goddard in rocket science?

Back

He is considered the father of modern rocketry for his pioneering work in developing liquid-fueled rockets.
