Unbalanced Forces Notes #1 Newton’s 1st law! Objects in motion...
Mass resists acceleration Example Full shopping cart vs. empty shopping cart The greater the mass the more force it takes to accelerate the object Acceleration is inversely proportional to mass Acceleration ~ 1 mass As the denominator increases the whole quantity decreases
Ten times as much
Newton’s Second Law The acceleration produced by the force on an object is directly proportional to the magnitude of the net force, is in the same direction as the net force and is inversely proportional to the mass of the object Mathematically: acceleration~ net force mass
nd 2 Newton’s Law in Mullisen’s words... The harder you push, the faster it accelerates – BUT – if it’s massive, it doesn’t accelerate as much. Acceleration = How hard you push How massive it is acceleration = net force mass
Baby Hippo Physics You throw a baby hippo upward with a force of 1000 Newtons. The baby hippo’s mass is 500 kg Acceleration ? = 1,000 newtons up 500 kilograms Answer: 2 m/s/s From the beginning of your throw to the end of your throw (which took 1 second), the baby hippo accelerated from 0 m/s to 2 m/s
Baby Hippo Physics Now you strap the baby hippo to a rocket. The rocket burns for 12 seconds, and propels the baby hippo with a force of 3,000 Newtons. Acceleration = 3,000 N 500 kg Answer: a = 6 m/s/s Every second the rocket burns, the baby hippo goes 6 m/s faster. After 12 seconds, he’s going 72 m/s (161 mph)
Baby Hippo Physics Now you throw the baby hippo’s mom upward with a force of 1,000 Newtons. Her mass is 4,500 kg. Acceleration ? = 1,000 newtons up 4,500 kilograms Answer: a = .22 m/s/s From the beginning of your throw to the end of your throw (which took 1 second), the mommy hippo accelerated from 0 m/s to .22 m/s
Newton’s 3rd Law of Motion For every action there is an equal and opposite reaction. Examples: You jump off a small boat. Oxygen tank in outer space. You sitting in your chair. JetLev Water Rocket Pack
