Physics Form 4 Subtopic 2.6 Force

Choose the correct statement(s) for force.

• Force is always visible.

• Force is a vector quantity, meaning it has both magnitude (strength) and direction.

• Force is measured in Newtons (N) and is calculated using the equation F = ma (force equals mass times acceleration).

• Force is a push or pull that can cause an object to accelerate, slow down, or change its direction of movement.

• Force is always positive.

Choose the graph(s) that involved in the force.

• 
• 
• 
• 

Choose law(s) that have been introduced in force.

• Second Law of Thermodynamics

• Newton's Second Law of Motion

• Second Law of Kirchhoff's Circuit Laws

Choose the correct statement(s).

• F = ma

  F is the force.

  m is the magnitude.

  a is the change of velocity over time.

• Acceleration is directly proportional to the force.

• Acceleration is inversely proportional to the mass.
  Acceleration will be increase when the mass increase.

• Acceleration is inversely proportional to the mass.
  Acceleration will be increase when the mass decrease.

Choose the correct SI unit for quantity in the force.

• SI unit of force, F is Newton (N).

• SI unit of time, t is millisecond (ms).

• SI unit of mass, m is gram (g).

• SI unit of acceleration, a is meter per second squared (m/s^2).

• SI unit of mass, m is kilogram (kg).
