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.

2.

FLASHCARD QUESTION

Front

Define mass in the context of physics.

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg). It is a scalar quantity and does not change regardless of the object's location.

3.

FLASHCARD QUESTION

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is a vector quantity and is measured in meters per second squared (m/s²).

4.

FLASHCARD QUESTION

Front

Explain the relationship between mass and acceleration according to Newton's Second Law.

Back

According to Newton's Second Law, mass and acceleration are inversely proportional. As mass increases, acceleration decreases if the net force remains constant.

5.

FLASHCARD QUESTION

Front

What is the formula to calculate acceleration?

Back

The formula to calculate acceleration (a) is: a = F/m, where F is the net force applied to the object and m is its mass.

6.

FLASHCARD QUESTION

Front

If a car is moving at a constant speed, what is its acceleration?

Back

The acceleration of a car moving at a constant speed is 0 m/s², as there is no change in velocity.

7.

FLASHCARD QUESTION

Front

What does it mean for two quantities to be directly proportional?

Back

Two quantities are directly proportional if one quantity increases, the other also increases, and vice versa. In the context of Newton's Second Law, net force and acceleration are directly proportional.
