Pushes and Pulls
Aligned to K-PS2 — Next Generation Science Standards.
What this lesson teaches
A push or a pull is a force that can make things start moving, stop, speed up, slow down, or change direction. Stronger pushes cause bigger changes.
Worked example
Pushing a toy car gently makes it roll slowly; pushing harder makes it go faster and farther.
Practice questions
- Give an example of a push and a pull.
- What happens to a ball if you push it harder?
- How can you make a rolling ball stop?

Empujar y jalar
Empujar o jalar son fuerzas que pueden hacer que los objetos comiencen a moverse, se detengan, aceleren, frenen o cambien de dirección. Los empujones más fuertes causan cambios más grandes.
Ejemplo: Empujar un carrito de juguete suavemente hace que ruede despacio; empujarlo con más fuerza hace que vaya más rápido y más lejos.
