NATURE OF FORCE

By Meagan, Kevin, Conor, Emrick
How is a Force Described?


A force is used to describe how a mass (object)is affected; in
the from of net, acceleration, balanced, unbalanced.
Force can also be described using the motions pull or push, that
can cause the object to change its velocity. It could make
something start & stop moving, and change it’s motion.
Unbalanced & Balanced Force


The Balanced force is a force
that is when equal forces are
acting on both sides of a
mass(or an object).
The unbalanced force is the
opposite of a balanced
force. An unbalanced force is
where the force on each side
of the object is uneven or not
equal.
How are Balanced & Unbalanced
Forces related to an Objects Motion?
Acceleration Force, Net Force


Acceleration is a force that…
The Net force is…
How do you calculate Acceleration &
what kind of Motion does it refer to?

…
Gravity & the Newton
Why do objects accelerate during freefall?




A Newton is a unit of force that was named after Isaac Newton
the man who recognized that the force of gravity existed.
It can determine how much something is weighed down by the
force of gravity.
For example, if an apple weighed 50N on earth it is going to
weigh differently on the moon because the gravity on the moon
is different and the newtons depend on the amount of gravity
that pulls them towards the planet.
Objects accelerate as they fall freely because
Mass & Weight


Mass is the amount of matter that the object has.
It’s weight is determined from how much gravity
pulls down on an object.
Projectiles & Friction
