Front

What is a Spiral Galaxy?

Back

A type of galaxy characterized by a flat, rotating disk containing stars, gas, and dust, often with a central bulge surrounded by spiral arms.

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 at a constant velocity unless acted upon by a net external force.

Front

What defines a compound?

Back

A substance made of two or more different elements that are chemically combined.

Front

How do you calculate acceleration?

Back

Acceleration (a) is calculated using the formula: a = net force (F) / mass (m).

Front

What are Gamma rays?

Back

Electromagnetic waves with the shortest wavelength and highest energy in the electromagnetic spectrum.

Front

What is the formula for Newton's Second Law of Motion?

Back

F = m * a, where F is the net force, m is the mass, and a is the acceleration.

Front

What is the difference between a mixture and a compound?

Back

A mixture is a combination of two or more substances that are not chemically combined, while a compound is made of two or more elements that are chemically bonded.

Front

What is inertia?

Back

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

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, influencing their motion.

Front

What is a net force?

Back

The overall force acting on an object when all the individual forces are combined.
