1.2.2 Weight and Mass

• Mass is measured in kilograms
• What are the units of weight?

  Newtons
• What is the definition of weight?

  Force due to gravity
• The formula relating weight, mass, and gravity is: Weight = Mass × Gravitational Acceleration
• What units are used to measure weight?

  Newtons
• Mass is measured in kilograms
• Weight is measured in newtons
• Mass changes depending on location.

  False
• Weight is calculated using the formula: Weight = Mass × Gravitational Acceleration
• Weight is measured in kilograms.

  False
• Gravitational acceleration is the same on all planets.

  False
• Weight is measured in Newtons
• Mass changes depending on location.

  False
• Weight depends on location.


  True
• The gravitational acceleration on Earth is approximately 9.8 m/s².
• Astronauts weigh less on the Moon due to its lower gravity
• What is the definition of mass?

  Amount of matter
• What is the approximate value of gravitational acceleration on Earth?

  9.8 m/s²
• Match the characteristic with its corresponding quantity:

  Amount of matter in an object ↔️ Mass

  Force due to gravity ↔️ Weight
• What units are used to measure mass?

  Kilograms or grams
• What is the definition of mass?

  Amount of matter
• What is the formula for calculating weight?

  Weight = Mass × Gravity
• Match the characteristic with its correct unit:

  Mass ↔️ Kilograms

  Weight ↔️ Newtons
• Match the symbol with its corresponding quantity:

  m ↔️ Mass

  W ↔️ Weight

  g ↔️ Gravitational Acceleration
• Understanding weight distribution can help prevent back injuries.


  True
• How does mass differ from weight in terms of location dependence?

  Mass is constant, weight varies
• Why does weight vary in space travel?

  Different gravitational acceleration
