FORCES
EFFECTS OF A FORCE
Make a moving object come to a stop.
Make a moving object slow down.
Make a stationary object start moving.
Make a moving object speed up.
Make a object change it’s shape.
Make a object change its size.
Make a moving object change direction.
Cannot see but touch and feel and see effects of forces.
CONTACT FORCE
Frictional Force
Can be reduced with a lubricant.
powder
oil
Lubricants reduce the friction between two surfaces.
Water
Can create heat.
Is created when two objects are in contact with each other and moving the opposite way of each other.
Other types of friction
Air resistance
Water resistance
How can we reduce water/air resistance?
Elastic Spring Force
increases when the spring is compressed or stretched more.
Original Length + Extension = Length of Spring
NON CONTACT FORCE
Magnetic Force
ATTRACT
Unlike Poles
Repel
Like poles
How can we measure the strength of a magnet?
STRONGER MAGNET
Attract the most steel paperclips.
Attract the paper clip from the furthest distance.
CHARACTERISTICS OF MAGNETS
Poles are Strongest part of the magnet.
WAYS TO WEAKEN MAGNETS
Heat the magnet.
Bang a hammer against the magnet repeated.
Drop the magnet repeatedly.
Gravitational Force
MASS
DEFINITION
The amount of substance in an object.
MEASURING UNITS
( KG) Kilograms
MEASURING INSTRUMENT
Beam balance
DOES NOT CHANGE.... when we go to another planet.
WEIGHT
DEFINITION
The gravitational force exerted on an object.
MEASURING UNITS
(N) Newton’s
MEASURING INSTRUMENT
Spring balance or force meter.
CHANGE.... when we go to a planet with a gravitational pull weaker or stronger than Earth’s.
