Fall Semester Review Honors 24-25

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Formula: F = ma.

Front

What is a chemical change?

Back

A chemical change occurs when substances combine or break apart to form new substances with different properties.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force.

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the shortest wavelength and highest energy. They are produced by radioactive atoms and in nuclear explosions.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength decreases, the frequency increases, and vice versa.

Front

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = ma, where 'm' is mass and 'a' is acceleration.

Front

What is the difference between a mixture and a solution?

Back

A mixture is a combination of two or more substances that retain their individual properties, while a solution is a homogeneous mixture where one substance is dissolved in another.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to temperature and heat.

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies toward each other, affecting the motion of objects, especially those in free fall.
