Balanced and unbalanced forces with explanations and examples

This video explains balanced and unbalanced forces with the help of real-life examples. When forces on an object are balanced, there is no change in speed or direction. To have unbalanced forces means that the force applied in one direction is greater than the force applied in the opposite direction. Let’s take an example of a pool table. When the forces acting on red pool balls are balanced, everything remains static. But as soon as the white ball strikes the red balls, forces become unbalanced and the balls move in the direction of a force. The real-life examples of a tennis ball, a car hitting another car, and weightlifting are not only relatable but also visually appealing. The cool illustrations will keep the students engaged throughout the video.

This video satisfies the 3-PS2-1 requirement for third-grade science proficiency.

Students who demonstrate understanding can:

3-PS2-1. Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
