Force and Motion

By Gianna, Owen, Claire,
and Colin
Force
 Force
is a push or a pull
 Force can cause something to speed
up, to slow down to change direction,
or to stop moving
 Ex. An example of force is when a
roller coaster is going down the hill
Gravity
 Gravity
is force that is always
working on objects on Earth. It
is the force that pulls us and
everything around us toward
the center of the Earth.
 An apple falling from a tree is
an example of gravity.
Gravitation
 Gravitation
is different than
gravity. It is the universal pull of
all objects on one another, causing
them to move closer together.
 Objects with larger masses have a
greater pull. As distance between
objects increases, gravitational
pull decreases.
Newtons
 All
force is measured in
newtons.
 A Newton is a metric unit for
forces including weight.
Motion
 Motion
is measured by the
change of position of an object.
 One example of motion is a ball
rolling down a hill. During such
motion, the ball’s kinetic energy
is increasing and its potential
energy is decreasing.
Speed
 Speed
is the measure of how far
something moves during a
certain period of time.
 Speed = distance divided by
time.
Average Speed
 Average
Speed is the measure of
the total distance of an object
has moved div i d e d b y t h e t o t a l
t i m e el a p s e d.
Velocity
 Velocity
is the speed of an object
with a given direction.
 In physics, velocity is the
measurement of the rate and
direction of change in position o
an object.
Acceleration
 Acceleration
is the rate of
change in velocity. This can be a
change in speed, direction, or
both.
Momentum
 Momentum
velocity.
is mass times
