Lesson: Newton’s First Law of Motion Mathematics

In this lesson, we will learn how to solve problems using Newton’s first law.

Lesson Plan

Students will be able to

recall and state Newton’s first law of motion,
find missing forces acting on a body at rest using Newton’s first law of motion,
solve real-world problems involving a body moving at a constant speed using Newton’s first law of motion.

Q1:

In the given figure, the body is moving with uniform velocity under the action of a system of forces. Given that the forces are measured in newtons, find the magnitudes of and .

Q2:

In the given figure, the body is subject to the action of a system of forces. Given that it is moving at a constant speed and that the forces are measured in newtons, find and .

Q3:
