PPT-Forces, Momentum, & Gravity

Chapter 3 In chapter 2 we studied motion but not its cause In this chapter we will look at both force and motion the cause and effect We will consider Newtons Newtons three laws of motion. An object of mass . m. traveling at velocity has a linear . momentum. (or just momentum), , given by . Units have no special name: kg-m/s. With no net force on a particle, its momentum is constant (Newton #1), but any force will change its momentum. nd. Law of Motion. Newton’s 2. nd. Law of Motion:. . acceleration of an object is in the same direction as the net force on the object. Newton’s 2. nd. Law of Motion . connects . force. , . mass. Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases.

The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity.. What is Momentum? Unit 8 Section 3 Momentum Momentum is a property of ALL moving objects Momentum is the product of the mass and velocity of an object. Momentum = mass x velocity ( P=M x V) Momentum is labeled as kg x m/s with a direction. Physics 101 Today -- Chapter 6: Momentum 2 nd Homework due tomorrow Momentum = “inertia in motion” Specifically, momentum = mass x velocity = m v Eg. Just as a truck and a roller skate have different inertia, when they are moving, they (generally) have different momenta. MOMENTUM Specification Forces and motion Forces, movement, shape and momentum know and use the relationship: momentum = mass × velocity p = m × v use the ideas of momentum to explain safety features What is Momentum? Momentum may be defined by its equation: Momentum is a quantity defined as the product of the mass and velocity of an object. Unit of Momentum The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity. Chapter 4. 4-1 Accelerated Motion. Newton’s Second Law of Motion:. Definition: . A net force acting on an object causes the object to accelerate in the direction of the force.. The magnitude of acceleration is affected by the size of the force and the mass of the object. Convert the following to scientific notation. Distance from Sun. : 92,960,000 . miles ____. Estimated Age of universe – 14,000,000,000. Convert the following to standard form. Speed of light = 9.0 * 10. Thomas Lund. NorthWest. Research Associates. Boulder, CO.
