Question

"Newton's second law of motion (we will cover in Chapter 4) says that the mass of an object times its acceleration is equal to the net force on the object. Which of the following gives the correct units for force?" a. (kg² x m) / s b. (kg) / (m x s²) c. (kg x m²) / (s²) d. (kg x m) / (s²) e. (kg x m²) / s

Answer 1

The correct units for force are given by option d. (kg x m) / (s²). Newton's second law of motion states that the mass of an object times its acceleration is equal to the net force on the object. The units for force are derived from the units for mass and acceleration.

The correct units for force are given by option d. (kg x m) / (s²).

Newton's second law of motion states that the mass of an object times its acceleration is equal to the net force on the object. Based on this equation, the units for force can be derived using the units for mass, acceleration, and force.

1. The units for mass are typically represented by kilograms (kg).
2. The units for acceleration are typically represented by meters per second squared (m/s²).
3. By rearranging the equation, we can solve for force and determine its units:

Force = mass x acceleration

Force = kg x m/s²

Therefore, the correct units for force are (kg x m) / (s²).
