SCIENCE "Forces and movement"

    

   Force is just a fancy word for pushing or pulling. If I push on something or pull on it, then I am applying a force to it. Force makes things move or, more accurately, makes things change their motion. Two natural forces that we have experienced are the force of gravity and magnetic forces.


These two forces act at a distance and do not require direct 

contact between the objects to function. 






MAGNETIC FORCES
                     Gravity produces a force that pulls objects towards each other, like a person towards the ground.

It is the force that keeps the Earth revolving around the sun 

and it's what pulls you toward the ground when you trip.
