Newton's Second Law: Acceleration StudyJam

Learning Resource Type

Subject Area

Science

Grade(s)

8

Overview

Acceleration is a change in velocity. That means acceleration can mean a change in speed or direction. Acceleration can be thought of as an object’s change in velocity over time.

The classroom resource provides a video that will explain Newton's Second Law of Motion. This resource can provide background information for students before they conduct their own demonstrations. There is also a short test that can be used to assess students' understanding.

SC15.8.9

Use Newton’s second law to demonstrate and explain how changes in an object’s motion depend on the sum of the external forces on the object and the mass of the object (e.g., billiard balls moving when hit with a cue stick).

UP:SC15.8.9

Vocabulary

  • Sir Isaac Newton
  • Newton's Second Law of Motion
  • Mass
  • Acceleration
  • Potential energy
  • Kinetic energy
  • Force
  • External force
  • Sum
  • Motion

Knowledge

Students know:
  • The acceleration of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change.
  • The greater the mass of the object, the greater the force needed to achieve the same change in motion.
  • For any given object, a larger force causes a larger change in motion. Force = mass x acceleration; F=ma.

Skills

Students are able to:
  • Demonstrate Newton's second law.
  • Articulate a statement that relates a given phenomenon to a scientific idea, including Newton's second law and the motion of an object.

Understanding

Students understand that:
  • Newton's Second Law states that changes in an object's motion depends on the sum of the external forces on the object and the mass of the object.
