PPT-Science 8 Chapter 2-The Laws of Motion

Newtons First Law Lesson 2 1 What causes an object in motion to remain in motion friction inertia gravity velocity 1 What causes an object in motion to remain in motion. In Massachusetts those laws are set forth in a complex statutory framework that can be difficult to interpret and that causes much confusion among employ ers Among the questions that employ ers struggle with are Can I open on Sunday Do I need to pro To describe different Jewish food, purity and Sabbath Laws with examples. To explain why it was important to keep these laws. To evaluate how difficult it is to keep Sabbath Laws. Why would any religion have “purity” laws to follow?. Background information: what students needed to know. How to calculate velocity. Newton’s 3 Laws of Motion. Kinetic and static friction. Momentum. Making sketches. EDP steps . As engineers for a toy manufacturing company, students were expected to:. Simple version of Newton’s three laws of motion. Newton’s Laws and the Mousetrap Racecar. 3. rd. Law: “for every action there is an equal and opposite reaction”. Is more mass a good thing or a bad thing for a mousetrap racecar to go far?. Kinematics Terminology. Scalar vs. Vector. Scalar: . quantities that have only a size, but no direction. i. e. : . distance, speed. Vector: . quantities that have a size and direction. ie. : . displacement, velocity. Housekeeping. Newton’s . First Law of . Motion. Newton’s Second Law of . Motion. Newton’s Third Law of Motion. Glossary. Inertia. is the property of objects that makes them resist changes in their motion. So, the greater the mass of an object, the more inertia it has. For example, it takes a much . Forces. Forces can be thought of as pushes and pulls. Examples. You exert a force on a door to open it (a push). Gravity exerts a force on you which holds you to the surface of the earth (a pull). Forces. Examples:. Pendulum.. Oscillating spring (either horizontal or vertical) without friction.. Point on a wheel when viewed from above in plane of wheel.. Physics Classroom has a good lesson on simple harmonic motion under Waves, vibrations.. © 2016 Pearson Education, Inc.. Goals for Chapter 9 . To study angular velocity and angular acceleration.. To examine rotation with constant angular acceleration.. To understand the relationship between linear and angular quantities.. 5-1 Uniform Circular Motion. Uniform Circular Motion. : The motion of an object traveling at a constant (uniform) speed on a circular path. 5-1 Uniform Circular Motion. Since we are dealing with object moving in a circle, it is convenient to talk about the . Dynamics is the study of force and its effect of motion.. A force is a push or pull that can change the inertia of an object.. Newton’s First Law of Motion. Every body continues in its state of rest or motion, unless acted upon by a force.. Gravity. Gravity. There’s a lot about you that’s attractive!. At this very moment, you are exerting an attractive force on everything around you. Your desk, your classmates, even planets millions of kilometers away!. Apologeticindb 26720/03/2017 1548 Describing motion is occasionally difficult to do with words. Graphs can help simplify this description greatly. Position = Distance from a starting point. Velocity = rate of change in position. Acceleration = rate of change in velocity.
