Balanced & Unbalanced Forces
Fun Facts
- The Earth is a contact force pushing up against an object that is being pulled down due to gravity.
- Gravity is an example of a force that pulls all objects toward the center of the Earth, like when jumping on a trampoline.
- Rocket scientists must be very careful about the direction of the force when launching a rocket for a mission to be successful.
Why Do We Need To Know About Force
Learning about forces helps us understand why things move and why jobs like designing planes need exact math. Forces are important whether you’re playing sports or sending rockets to space. They matter in many parts of life and work.
Knowing about forces lets us change how things in the world work, like controlling a bike or winning at tug-of-war by using forces in smart ways. This knowledge is important not just for science and engineering jobs but also for understanding how things around us work every day.
