Remediation Newton's Second Law Calculations

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.

Front

What is the formula to calculate force?

Back

The formula to calculate force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula: p = m * v, where m is mass and v is velocity.

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).

Front

If an object has a mass of 10 kg and accelerates at 5 m/s², what is the force applied?

Back

50 Newtons (F = m * a = 10 kg * 5 m/s²).

Front

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

Back

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

Front

What is the acceleration of an object at rest?

Back

The acceleration of an object at rest is 0 m/s².

Front

If a 0.5 kg object is moving at 2 m/s, what is its momentum?

Back

1 kg-m/s (p = m * v = 0.5 kg * 2 m/s).

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 = m * a).

Front

What is the mass of an object if a force of 20 N produces an acceleration of 4 m/s²?

Back

5 kg (m = F/a = 20 N / 4 m/s²).
