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 = m × a.

2.

FLASHCARD QUESTION

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula a = F/m, where F is the net force applied to the object and m is its mass.

3.

FLASHCARD QUESTION

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

4.

FLASHCARD QUESTION

Front

If a force of 20 N is applied to a mass of 50 kg, what is the acceleration?

Back

0.4 m/s² (using the formula a = F/m, where a = 20 N / 50 kg).

5.

FLASHCARD QUESTION

Front

What is the mass of an object if a force of 250 N results in an acceleration of 5 m/s²?

Back

50 kg (using the formula m = F/a, where m = 250 N / 5 m/s²).

6.

FLASHCARD QUESTION

Front

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

Back

The relationship is defined by Newton's Second Law: F = m × a, meaning force equals mass times acceleration.

7.

FLASHCARD QUESTION

Front

How much force is needed to accelerate a 2.55 kg toy car at 6.00 m/s²?

Back

15.3 N (using the formula F = m × a, where F = 2.55 kg × 6.00 m/s²).
