2.5 Newton's Second Law

• The acceleration of an object is inversely proportional to its mass according to Newton's Second Law.

  True
• Match the component with its definition and unit:

  Force (F) ↔️ The net force acting on an object, measured in Newtons (N)

  Mass (m) ↔️ The mass of the object, measured in kilograms (kg)

  Acceleration (a) ↔️ The acceleration of the object, measured in m/s²
• If a 2 kg ball is pushed with a net force of 10 N, its acceleration is 5 m/s²
• If the mass of an object increases, its acceleration increases for the same net force.

  False
• Newton's Second Law of Motion states that the net force acting on an object is equal to the product of its mass and acceleration
• The amount of matter in an object is referred to as its mass
• Acceleration decreases with increasing mass, according to Newton's Second Law.

  5 m/s²
• If the net force on an object doubles, its acceleration also doubles according to Newton's Second Law.


  True
• The mathematical expression for Newton's Second Law is $F =$$ma$


  True
• Match the components of Newton's Second Law with their definitions:

  Force (F) ↔️ Net force acting on an object

  Mass (m) ↔️ The amount of matter in an object

  Acceleration (a) ↔️ The rate of change of velocity
• What is the acceleration of an object with a mass of 2 kg subjected to a net force of 10 N?
