Laws of Motion

• What is mass defined as?

  Amount of matter
• What does Newton's first law of motion state about an object at rest?

  It stays at rest
• Match the term with its definition:

  Rest ↔️ Object is not moving

  Motion ↔️ Object is moving

  Force ↔️ Changes object's motion
• What is the formula for Newton's second law of motion?

  $F =$$ma$
• What is the unit for acceleration?

  m/s²
• Match the term with its definition:

  Action ↔️ Force applied to an object

  Reaction ↔️ Equal and opposite force
• Steps to apply Newton's laws of motion to solve problems

  1️⃣ Identify forces acting on the object

  2️⃣ Apply Newton's second law (F = ma)

  3️⃣ Use kinematic equations
• A 5 kg box is pushed with a force of 20 N. What is the acceleration of the box?

  4 m/s²
