Newton's Second Law Quiz

What is the unit of mass?

• grams (g)

• pounds (lb)

• kilograms (kg)

• ounces (oz)

If an object has a mass of 4 kg and accelerates at 2 m/s², what is the force applied?

• 6 N

• 8 N

• 10 N

• 12 N

• The speed of the object, measured in meters per second (m/s).

• The force acting on the object, measured in newtons (N).

• The mass of the object, measured in kilograms (kg).

• The acceleration of the object, measured in meters per second squared (m/s²).

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

• The greater the mass of an object, the more force is required to accelerate it.

• Force is independent of mass and acceleration.

• Acceleration is directly proportional to mass and inversely proportional to force.

• Mass and acceleration are unrelated to force.

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

• The acceleration increases.

• The acceleration decreases.

• The acceleration remains the same.

• The acceleration becomes zero.

What does the symbol 'F' represent in the formula @@F = ma@@?

• The mass of the object, measured in kilograms (kg)

• The acceleration of the object, measured in meters per second squared (m/s²)

• The net force applied to an object, measured in Newtons (N)

• The distance traveled by the object, measured in meters (m)

If a force of 10 N is applied to a mass of 2 kg, what is the acceleration?

• 2 m/s²

• 5 m/s²

• 10 m/s²

• 20 m/s²

What is Newton's Second Law of Motion?

• 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@@.

• Newton's Second Law states that an object at rest will remain at rest unless acted upon by an external force.

• Newton's Second Law states that for every action, there is an equal and opposite reaction.

• Newton's Second Law states that the velocity of an object is constant unless acted upon by a net force.

Which formula is incorrect: @@F = ma@@, @@M = \frac{F}{A}@@, @@A = \frac{F}{M}@@, @@M = \frac{A}{F}@@?

• @@F = ma@@

• @@M = \frac{F}{A}@@

• @@A = \frac{F}{M}@@

• @@M = \frac{A}{F}@@

What is the unit of force?

• Pound (lb)

• Newton (N)

• Joule (J)

• Pascal (Pa)
