up and hands in the air. Here we go...Discover all about motion
and force in this section.
MOTION
Motion
of an Object
Learn that the motion of an object can be described by its
position, direction of motion and speed.
Vibrations
Learn that vibrations in material set up wave disturbances
that spread away from the source (e.g. sound and earthquake
waves).
FORCE
No
Contact Forces
Learn that many forces (e.g. gravitational, electrical and
magnetic) act at a distance (i.e. without contact).
Contact
Forces
Learn the common contact forces.
Multiple
Forces
Learn that if more than one force acts on an object, then
the forces can reinforce or cancel each other depending on
direction and magnitude.
Simple
Machines
Learn that simple machines can be used to change the direction
or size of a force.
In
Motion and at Rest
Learn that an object in motion will continue at a constant
speed and in a straight line until acted upon by a force and
that an object at rest will remain at rest until acted upon
by a force.
Net
Force
Learn the ways in which a net force (i.e. the sum of all acting
forces) can act on an object (e.g., speeding up and object
traveling in the same direction as the net force, slowing
down an object traveling in the direction opposite of the
net force).
Gravity
Learn that gravity is a universal force that every mass exerts
on every other mass.
