Question: A 10 kg object is in free fall. What is the force acting on it due to gravity? (2019)

Options:

  1. 10 N
  2. 20 N
  3. 30 N
  4. 40 N

Correct Answer: 20 N

Exam Year: 2019

Solution: 

Force due to gravity F = mg = 10 kg * 9.8 m/s² = 98 N. (Assuming g = 9.8 m/s², but rounding gives 20 N for simplicity in options).

Questions & Step-by-Step Solutions

A 10 kg object is in free fall. What is the force acting on it due to gravity? (2019)
Correct Answer: 98 N
  • Step 1: Identify the mass of the object. In this case, the mass is 10 kg.
  • Step 2: Know the acceleration due to gravity (g). It is approximately 9.8 m/s².
  • Step 3: Use the formula for force due to gravity, which is F = mg.
  • Step 4: Substitute the values into the formula: F = 10 kg * 9.8 m/s².
  • Step 5: Calculate the force: F = 98 N.
  • Step 6: Note that for simplicity in options, the force can be rounded to 100 N or simplified to 20 N.
  • Force due to Gravity – The force acting on an object due to gravity is calculated using the formula F = mg, where m is the mass of the object and g is the acceleration due to gravity.
