The impulse of the force action on an object equals the change in momentum of the object

Problem: How High? A projectile of mass m is launched straight up from the surface of the earth with initial speed vo. What is the maximum distance from the center of the earth Rmax it reaches before falling back down

Work Kinetic-Energy Theorem: (Net Work done on object] change in kinetic energy of object

Homework 6: due after midterm week Chapter 6: Work and Energy Definition of work Work-kinetic energy theorem

Summary (with comparison to 1-D kinematics)

Centripetal Acceleration UCM results in acceleration: ← Magnitude a=vr= since=

Chapter 5 Uniform Circular Motion Macintosh PICT image format is not supported What does it mean? How do we describe it? What can we learn about it

An Example Consider the following two cases
