Learning Objective
I can use Newton's Second Law to solve problems involving force, mass, and acceleration.
- 1
Newton's Second Law explains that unbalanced forces cause objects to speed up, slow down, or change direction.
- 2
Newton's Second Law can be expressed with the equation: Resultant Force = mass x acceleration, where force is measured in Newtons, mass in kilograms, and acceleration in meters per second squared.
- 3
If the force from your arm is the same, but the mass of an object is much bigger, its acceleration will be smaller.
