8.9 Newton's Second Law of Motion Test (GL)

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula: F = m * a.

Front

What is the formula to calculate force?

Back

The formula to calculate force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What unit is force measured in?

Back

Force is measured in Newtons (N).

Front

What does mass refer to in physics?

Back

Mass refers to the amount of matter in an object, typically measured in kilograms (kg).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

If two objects are pushed with the same force, what determines which one accelerates more?

Back

The object with the smaller mass will accelerate more when pushed with the same force, according to Newton's Second Law.

Front

True or False: 1 Newton is equal to 1 kg·m/s².

Back

True.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is defined by Newton's Second Law: Force equals mass times acceleration (F = m * a).

Front

If an object has a mass of 10 kg and accelerates at 3 m/s², what is the force applied?

Back

The force applied is 30 N (calculated using F = m * a).

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

If the mass increases while the force remains constant, the acceleration decreases.
