A natural

pulls all objects toward
the center of the earth.
WHAT IS A FORCE?
A pull or a push
on an object
Which do you think would fall first?
•
A
bouncy
ball
Or a marble
Try It!
They fall at the same rate of speed,
but
the marble has more mass
(weight) and so gravity makes it fall
harder!
Gravity has a stronger force on
things with more mass!
It takes a force to overcome
gravity!
Throw a bean bag in the air
and then…
Throw a basketball in the air.
Which one was harder
to throw?
•
You had to use more force
to throw the basketball
because it has more mass
(weight)

Gravity is a natural force that pulls objects towards the Earth's center, affecting how they fall based on mass. This presentation explores what gravity is, the impact of forces on objects, and how mass influences the effect of gravity. It demonstrates how objects like a bouncy ball and a marble fall differently due to their mass and highlights the need for force to overcome gravity in situations like throwing a bean bag versus a basketball. The content also mentions a resource for educational powerpoints on teaching physics concepts.
