FORCE AND MOTION  BALANCED AND UNBALANCED FORCES 100N 200N 200N 400N 100N Net Force: 600N Net Force: 0N Direction of motion: RIGHT Direction of motion: NONE FORCE  Galileo Galilei – He observed the objects in free fall have the same constant acceleration regardless of their weight. SIR ISAAC NEWTON  NEWTON’S LAWS OF MOTION LAW OF LAW OF ACTION LAW OF INERTIA AND REACTION ACCELERATION An object at rest will tends to stay at rest, and an object in motion with the same direction and speed. FIRST LAW OF MOTION  NEWTON’S LAWS OF MOTION LAW OF LAW OF ACTION LAW OF INERTIA AND REACTION ACCELERATION The acceleration An object at rest will produced by a net force on tends to stay at rest, and a body is directly an object in motion with proportional to the the same direction and magnitude of the net force speed. and inversely proportional to the mass of the body. SECOND LAW OF MOTION Acceleration = Force/mass 10 N 35 N 2 meters 8 meters More mass = Less acceleration Less mass = More acceleration  EXAMPLE: How much force is needed to accelerate a 50kg rider and his 250kg motorcycle at 4m/s2? F = 1200 Newtons  kg Given: Formula: m=25kg a=4m/s2 F = ma F = 25kg x 4m/s2 F = 100 kg m/s2 or N  You are pushing a friend on a sled. You push with a force of 40 N. Your friend and the sled together have a mass of 80 kg. What is the acceleration of your friend on the sled? Given: Formula: F = 40 N F = ma m=80kg a=F/m a=F/m a=40N/80kg a=0.5m/s2 If the blue one has a smaller mass than the yellow one, which one will have the larger acceleration? F F  NEWTON’S LAWS OF MOTION LAW OF LAW OF ACTION LAW OF INERTIA AND REACTION ACCELERATION The acceleration An object at rest will produced by a net force on For every action, tends to stay at rest, and a body is directly there is an equal but an object in motion with proportional to the opposite reaction the same direction and magnitude of the net force force. speed. and inversely proportional to the mass of the body. THIRD LAW OF MOTION THIRD LAW OF MOTION THANKS!
