Question

In metric units, forces are measured in "newtons," which can also be written as kilograms $\times$ meters/second $^{2}$. What is the acceleration experienced by a 100 -kg mass if a 100 -newton force is applied to it? What is the acceleration experienced by a $200-\mathrm{kg}$ mass if the same force is applied to it?

Step 1

1) For the 100-kg mass: We are given the force F = 100 N and the mass m = 100 kg. We need to find the acceleration a. Using the formula, we can write: 100 N = 100 kg * a To solve for a, we can divide both sides of the equation by 100 kg: Show more…

Key Concepts

SI Units of Force

In the International System of Units, force is measured in newtons, where one newton is defined as the amount of force needed to accelerate a one-kilogram mass by one meter per second squared. This unit definition directly ties the concepts of force, mass, and acceleration together.

Mass and Acceleration Relationship

When a constant force is applied, the acceleration experienced by an object is inversely proportional to its mass. This means that a smaller mass will accelerate more than a larger mass under the same applied force, which is a key concept when analyzing the dynamics of different objects.

Newton's Second Law

Newton's Second Law establishes that the force acting on an object is equal to the mass of the object times its acceleration (F = ma). This fundamental law shows the direct proportionality between force and acceleration, meaning that for a constant force, the acceleration is inversely proportional to the mass.
