Questions & Step-by-Step Solutions
A force of 10 N is applied to an object, causing it to accelerate at 2 m/s². What is the mass of the object? (2020)
Step 1: Identify the formula to use. The formula is F = ma, where F is force, m is mass, and a is acceleration.
Step 2: Rearrange the formula to solve for mass (m). This gives us m = F/a.
Step 3: Plug in the values. We have F = 10 N and a = 2 m/s².
Step 4: Calculate the mass. Substitute the values into the equation: m = 10 N / 2 m/s².
Step 5: Perform the division. 10 N divided by 2 m/s² equals 5 kg.
Step 6: State the final answer. The mass of the object is 5 kg.
Newton's Second Law of Motion – This law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).
