Questions & Step-by-Step Solutions

Calculate the weight of a 10 kg object on the surface of the Earth (g = 9.8 m/s²).
  • Step 1: Identify the mass of the object. In this case, the mass (m) is 10 kg.
  • Step 2: Identify the acceleration due to gravity on Earth. This value (g) is 9.8 m/s².
  • Step 3: Use the formula for weight, which is Weight (W) = mass (m) * gravity (g).
  • Step 4: Substitute the values into the formula: W = 10 kg * 9.8 m/s².
  • Step 5: Calculate the result: W = 98 N.
  • Weight Calculation – Weight is the force exerted by gravity on an object, calculated as the product of mass and gravitational acceleration.
  • Units of Measurement – Understanding the difference between mass (kg) and weight (N) is crucial for correct calculations.
