Newton's Second Law of Motion

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.

Front

What does the formula F=MA represent?

Back

F=MA represents the relationship between force (F), mass (M), and acceleration (A). It indicates that force equals mass times acceleration.

If a 10 kg object is accelerated upward at 2 m/s², what force is required?

Back

20 N

Front

What is the force required to accelerate a 20 kg bike at 10 m/s²?

Back

200 Newtons

Front

According to Newton's Second Law, how is acceleration calculated?

Back

Acceleration is calculated by dividing the net force acting on an object by the object's mass.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

If a 50 kg bicycle accelerates at 2 m/s², what is the force applied?

Back

100 N

Front

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

Back

The unit of force is the Newton (N).

Front

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

Back

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

Front

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

Back

The relationship is that force is equal to mass multiplied by acceleration (F=MA).
