The Affect of Forces on Motion
5-5.1
A push or a pull
FORCE
What forces can affect motion?
MagnetismGravityFriction
What are the four ways that force can affect motion?
Slow things down,Speed things up,
Stop thingsChange their direction
A force that acts at a distance and cannot be seen. It comes from the
furthest regions of the Earth.
Magnetism
Materials that have magnetic force
MAGNETS
Poles that are the same – S to S
and N to N . . .
REPEL
Opposite poles –
S to N and N to S
will . . .
ATTRACT
What happens to magnetic forces when they get closer?
THE GET STRONGER
Where is the greatest strength of magnetic forces on a magnet?
AT THE POLES
A pull that attracts one object to another
GRAVITY
When do you notice this attraction of one object to another?
WHEN THE OBJECT IS BIGlike a pencil to the Earth
What does the attraction of the Moon cause on the Earth?
TIDES
How does the Sun’s gravity affect the Earth?
KEEPS IT REVOLVING
The force that opposes motion when surfaces are touching
FRICTION
How can you make more friction?
MORE MASSRougher Surfaces
How can you reduce the affect of friction?
LUBRICATIONor
ROLLERS
In which states of matter does friction occur?
