Understanding Forces and Motion: Pushes, Pulls, and Magnetism

Explore the concepts of forces and motion in this educational unit. Learn how a force is a push or pull that causes an object to move, and discover the varying effects of force depending on distance and weight. Understand how magnets attract objects without contact and how gravity keeps everything grounded. Investigate the roles of friction and different surfaces, and examine how moving objects behave in a straight line unless acted upon. This unit provides a solid foundation for understanding these fundamental scientific principles.
