What is the force that makes objects move?
"The student is expected to demonstrate and observe how position and motion can be changed by pushing and pulling objects, such as tug of war, swings, balls, and wagon."
Learning objective:
Force is a push or pull on an object. Motion is a change in the position of an object over time. Forces cause objects to accelerate, slow down, or change direction.
Force and Motion
Force - a push or pull that can make an object move, speed up, slow down, or change direction. Motion - a change in position over time. Newton's Laws of Motion - three physical laws that describe the relationship between a body and the forces acting upon it.
Concepts:
The force of gravity on Earth is so strong that it can pull a feather and a bowling ball at the same rate. Gravity is the weakest of the four fundamental forces, yet it is the most dominant force in the universe. The force of friction can be used to generate electricity.

Work together in pairs: Q. What movement occurs when you pull or push an object, such as a tug of war rope, a swing, a ball, or a wagon?
Work together in pairs: Q: What is a force?A: A force is a push or pull that can make something move, speed up, slow down, or change direction.
