Questions & Step-by-Step Solutions

What is the gravitational force between two 1 kg masses separated by 1 meter?
  • Step 1: Identify the formula for gravitational force, which is F = G * (m1 * m2) / r^2.
  • Step 2: Identify the values needed for the formula: G (gravitational constant) = 6.67 x 10^-11 N(m^2/kg^2), m1 = 1 kg, m2 = 1 kg, and r = 1 meter.
  • Step 3: Substitute the values into the formula: F = 6.67 x 10^-11 * (1 * 1) / (1^2).
  • Step 4: Calculate the denominator: 1^2 = 1.
  • Step 5: Calculate the numerator: 6.67 x 10^-11 * 1 = 6.67 x 10^-11.
  • Step 6: Divide the numerator by the denominator: F = 6.67 x 10^-11 / 1 = 6.67 x 10^-11 N.
  • Step 7: Conclude that the gravitational force between the two 1 kg masses separated by 1 meter is 6.67 x 10^-11 N.
