Understanding the Concepts
* 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. Mathematically:
* F = m * a
* Where:
* F = Force (N)
* m = Mass (kg)
* a = Acceleration (m/s²)
Solving the Problem
1. Find the mass:
* We know F = 30 N and a = 5 m/s². Let's rearrange Newton's Second Law to solve for mass (m):
* m = F / a
* m = 30 N / 5 m/s²
* m = 6 kg
2. Calculate the force needed for 1 m/s² acceleration:
* We know the mass (m = 6 kg) and the desired acceleration (a = 1 m/s²). Let's use Newton's Second Law again:
* F = m * a
* F = 6 kg * 1 m/s²
* F = 6 N
Answer:
You would need a force of 6 N to give the object an acceleration of 1 m/s².
