Learn on PengiAmplify Science (California) Grade 8Chapter 2: Mass and Velocity

Lesson 3: Force, Mass, and Velocity

Key Idea.

Section 1

Constant Force, Variable Mass

Key Idea

To isolate the effect of mass, scientists perform experiments where the force remains constant while the mass varies.

Imagine a single engine attached to a small cart and then to a large truck. The "push" is identical. Observing the difference in outcomes highlights that mass is the deciding factor in how the motion changes.

Section 2

The Inverse Relationship

Key Idea

The experimental results reveal an inverse relationship.

As mass increases, the change in velocity decreases.
