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 (Force = mass × acceleration).

2.

FLASHCARD QUESTION

Front

How does mass affect acceleration when the same force is applied?

Back

When the same force is applied, an object with greater mass will have less acceleration compared to an object with less mass. This is because acceleration is inversely proportional to mass.

3.

FLASHCARD QUESTION

Front

What is net force?

Back

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

4.

FLASHCARD QUESTION

Front

What happens to an object at rest when unbalanced forces act on it?

Back

The object begins moving in the direction of the net force acting on it.

5.

FLASHCARD QUESTION

Front

If a 20 N force is applied to a 5 kg mass, what is the acceleration?

Back

The acceleration is 4 m/s², calculated using the formula a = F/m (acceleration = force/mass).

6.

FLASHCARD QUESTION

Front

How much force is needed to accelerate a 2 kg physics book to an acceleration of 6 m/s²?

Back

A force of 12 N is needed, calculated using the formula F = ma (Force = mass × acceleration).

7.

FLASHCARD QUESTION

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 = ma).
