• Newton’s first law of motion: an object at rest/motion will stay at rest/motion until a force acts on it. • Law of Inertia https: //www. youtube. com/watch? v=8 b-Mogqy 1 h 4 http: //www. aaronswansonpt. com/basic-biomechanics-newtons-laws-of-motion

• Newton’s second law of motion: how much an object accelerates depends on its mass and the force acting on it. • F= m/a F m a https: //www. youtube. com/watch? v=iw. P 4 he. WDhvw http: //popphysics. com/chapter-2 -newtons-laws/newtons-second-law-part-2 -multiple-forces/

• Newton’s third law of motion: Every action has an equal and opposite reaction. www. memecenter. com/fun/1815615/newton-amp-039 -s-th https: //www. google. com/url? sa=i&rct=j&q=&esrc=s&source=images&cd=&ved=0 ah.

• Newton’s Universal Gravitational Law: gravity is a force of attraction between all matter in the universe

• Newton’s Universal Gravitational Law: force of gravity is equal to the gravitational constant (G) multiplied the mass of the two objects (M, m). Divided by the distance between them squared (d 2) Directly Proportional: Mass to Fg Indirectly Proportional: Distance to Fg https: //www. youtube. com/watch? v=Jk 5 E-Cr.

Forces F=m*a Fg=GMm 2 d Which formula should we use to finish our yellow packet?

• Only the effect of a force can be seen. • Forces are measured in Newtons (N) • They usually act in pairs (1 st Law of motion/ Inertia) • They always act in certain direction • A newton meter is used to measure forces. Iffat Sardharwalla March 2010

Balanced and Unbalanced Forces Balanced Forces produce Unbalanced Forces NO change in Movement Direction of Moving Objects The forces on the person are balanced The floor pushes upward on the person Change the Speed and or Smaller Force Greater Force Gravity pulls downwards on the person Iffat Sardharwalla March 2010

Forces & Movement Forces are nearly always PUSHES and PULLS Iffat Sardharwalla March 2010

Forces can make objects do FIVE things 1. Speed up 2. Slow down 3. Change Direction Like kicking a ball Like drag or air resistance Like hitting a ball with a bat 4. Turn Like turning a spanner wrench 5. Change shape Like stretching, twisting, compressing and bending Iffat Sardharwalla March 2010
