Questions & Step-by-Step Solutions
A 3 kg object is subjected to a net force of 12 N. What is its acceleration?
Step 1: Identify the mass of the object, which is 3 kg.
Step 2: Identify the net force acting on the object, which is 12 N.
Step 3: Use the formula for acceleration, which is a = F/m.
Step 4: Substitute the values into the formula: a = 12 N / 3 kg.
Step 5: Calculate the acceleration: 12 N divided by 3 kg equals 4 m/s².
Newton's Second Law of Motion – This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
