Forces A force is when an object is pushed, pulled, stretched or squashed. Forces can change the: (a)speed of an object (b)shape of an object (c)direction.
Aim: What are Newtons 1 st and 3 rd Laws of Motion? Do Now: What is the weight of the box? m = 20 kg F g = mg F g = (20 kg)(9.8 m/s 2 ) F g = 196 N.
Objectives 1.Identify several forms of energy. 2.Calculate kinetic energy for an object. 3.Apply the work-kinetic energy theorem to solve problems. 4.Distinguish.
NEWTON’S 2 nd Law of Motion. Newton’s 2 nd law of Motion Describes the relationship of how something with a mass accelerates when it is pushed/pulled.
Chapter 4- Forces and Motion. Think about the following questions: What is this object? Where is it? Why does it look like that? IO is a moon of Jupiter.
