FLASHCARD QUESTION

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. It can be expressed with the formula: F = ma, where F is force, m is mass, and a is acceleration.

FLASHCARD QUESTION

Front

How does mass affect the force needed to move an object?

Back

As mass increases, the force required to move the object also increases, assuming the acceleration remains constant. This means heavier objects require more force to achieve the same acceleration as lighter objects.

FLASHCARD QUESTION

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

FLASHCARD QUESTION

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

5.

FLASHCARD QUESTION

Front

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

Back

The relationship is defined by Newton's Second Law: the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

FLASHCARD QUESTION

Front

What happens to acceleration if the force is doubled while mass remains constant?

Back

If the force is doubled while mass remains constant, the acceleration of the object will also double.

FLASHCARD QUESTION

Front

What happens to acceleration if the mass is doubled while force remains constant?

Back

If the mass is doubled while force remains constant, the acceleration of the object will be halved.
