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.

Content Standard(s):

Science
SC2015 (2015)
Grade: 8
Physical Science

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).

NAEP Framework

NAEP Statement::
P8.16a: Forces have magnitude and direction.

NAEP Statement::
P8.16b: Forces can be added.

NAEP Statement::
P8.16c: The net force on an object is the sum of all the forces acting on the object.

NAEP Statement::
P8.16d: A nonzero net force on an object changes the object's motion; that is, the object's speed and/or direction of motion changes.

NAEP Statement::
P8.16e: A net force of zero on an object does not change the object's motion; that is, the object remains at rest or continues to move at a constant speed in a straight line.

Disciplinary Core Idea: Motion and Stability: Forces and Interactions

Evidence Of Student Attainment:

Students:

Demonstrate, using Newton's Second Law, how changes in an object's motion depend on the sum of the external forces on the object and the mass of the object.
Explain, using Newton's Second Law, how changes in an object's motion depend on the sum of the external forces on the object and the mass of the object.

Teacher 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.
