" The acceleration of an object depends on the mass of the
object and the amount of force applied. "
realized that two things effected an object's acceleration.
#1: The size of the
force. ( How hard we push or pull.)
#2: The object's mass.
(The amount of matter of the object.)
Acceleration = net force divided by mass
are some examples:
|If you increase the net
force the acceleration will increase.
If Superman pushed on
a huge truck, with a net force of 25 N the truck
might move slightly.
But if his friends came to help
him and their total net force was 25ooN of force,
the truck would move much more.
If you increase the mass though,
the acceleration will decrease.
If I push on the feather with a
net force of 10 N the feather will sail through the
But if I apply that same 10N of
force to the sumo wrestler, he probably will not
