## Universal Forces 06-04-24 ### - Gravity - Attraction to an object because of their mass. - Air Resistance - Friction Resistance due to movement because of contact. - Electrostatic - Force between two charged objects - Magnetism - Attraction between a magnet and magnetic material - Upthrust - Force of an object in a liquid/gas pushing it up. - Water Resistance - Force on a moving object in water that slows it down ### Gravitational Forces - Mass - Amount of matter in an object (KG) - Mass does not change - Weight - A force caused by gravity (N) - 1KG = 10N on Earth - 1KG = 1.6667N on the moon ## - Cat = 5KG - Weight on the Earth - The Moon = 8.33 - Jupiter = 900N - To Weigh on the moon - To Weigh on Jupiter - Magnets - When you bring opposite magnets together they attract each other but the same ones repulse each other. - Plastic bag - Sinks - Cork - Floats - Ball - Bounces to get a force. - Balloon - Sticks ## Ball Diag - Air Resistance = 20 - Gravity = 70
