Newton’s Laws and the affects of force
Newton’s First Law **Explains balanced forces • Also known as the Law of Inertia
Newton’s First Law • Part 1 - Objects at rest, stay at rest. • 1. Until a force acts on them • 2. Friction puts objects at rest
Newton’s First Law • Part 2 - Objects in motion, stay in motion. • 1. Until a force acts on them • 2. Friction stops objects that are moving Air Friction and Gravity!
Newton’s 2 nd Law of Motion • • • Shows a relationship between Force, Mass, and acceleration. Force = mass x acceleration
Newton’s 2 nd Law of Motion • • • The more force the faster the acceleration. (direct relationship) pushing someone slow, acc. is slow pushing someone hard, acc. is fast **Explains unbalanced forces
Newton’s 2 nd Law of Motion • The more mass the slower the acceleration. • A heavy truck moves slower than a lighter truck.
Which will have a faster acceleration? Force = mass x acceleration Force = 20 kg x 5 m/s 2 Force = 20 kg x 10 m/s 2 Force = Increased force on 20 kg of mass gives more acceleration.
Which amount of mass is easier to accelerate? A horse carrying an empty wagon or a horse carrying a wagon full of hay? A horse carrying an empty wagon is easier to accelerate.
Newton’s 3 rd Law of Motion States that for every action there is an equal and opposite reaction. (Action-Reaction Forces)
Newton’s 3 rd Law of Motion You push on the ground and the ground pushes on you.
Newton’s 3 rd Law of Motion The oars push on water and the water pushes on the oars.
• Newton’s 3 rd Law of Motion Rocket expels expanding gases and gases push up on rocket. Newton’s Law Video
