Newton's First Law (Chapter 2 Lesson 2)

Newton's First Law (Chapter 2 Lesson 2)

Author: Emily Hoopman

Topic: Newton’s 1st Law of Motion

  • An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Essential Learning Targets:

  • I know what Newton’s first law is.
  • I know how motion is related to balanced and unbalanced forces.
  • I know how inertia effects the motion of an object. 

Key Concepts

•Unbalanced forces cause an object to move.
•According to Newton’s first law of motion, if the net force on an object is zero, the object’s velocity does not change.
•Inertia is a property that resists a change in the motion of an object.

Standards Recognize that when the forces acting on an object are balanced, the object remains at rest or continues to move at a constant speed in a straight line, and that unbalanced forces cause a change in the speed or direction of the motion of an object. Identify the forces acting on an object and describe how the sum of the forces affects the motion of the object. For example: Forces acting on a book on a table or a car on the road.

Science of NFL Football: Newton's First Law of Motion

"Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League. In this segment, NBC's Lester Holt breaks down Isaac Newton's First Law of Motion and how it can change how fast players can speed the football up or slow it down. Professors Tony Schmitz of the University of Florida and Jim Gates of the University of Maryland explain why the control of inertia is so vital to the outcome of the game.

Forces and Motion: Basics (Net Force)

Identify when forces are balanced vs unbalanced.
  • Determine the sum of forces (net force) on an object.
  • Predict the motion of an object with zero net force.
  • Predict the direction of motion given a combination of forces.


Newton's Laws: Crash Course Physics #5

I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us about just that.
