LEARNING OBJECTIVES By the end of this section, you will be able to: Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is…
LEARNING OBJECTIVES By the end of this section, you will be able to: Analytical methods of vector addition and subtraction employ geometry and simple trigonometry rather than the ruler and protractor of graphical methods. Part of the graphical technique is retained,…
LEARNING OBJECTIVES By the end of this section, you will be able to: Figure 3.7 Displacement can be determined graphically using a scale map, such as this one of the Hawaiian Islands. A journey from Hawai’i to Moloka’i has a number of…
LEARNING OBJECTIVES By the end of this section, you will be able to: Figure 3.2 Walkers and drivers in a city like New York are rarely able to travel in straight lines to reach their destinations. Instead, they must follow roads and…
Figure 3.1 Hitting a tennis ball is difficult enough when it is traveling at high speeds in a relatively straight line. However, most motion is in curved, rather than straight-line, paths. Tennis players must account for the arc of the ball and…
Displacement Vectors, Scalars, and Coordinate Systems Time, Velocity, and Speed Acceleration Motion Equations for Constant Acceleration in One Dimension Problem-Solving Basics for One-Dimensional Kinematics Falling Objects Graphical Analysis of One-Dimensional Motion
LEARNING OBJECTIVES By the end of this section, you will be able to: A graph, like a picture, is worth a thousand words. Graphs not only contain numerical information; they also reveal relationships between physical quantities. This section uses graphs…
LEARNING OBJECTIVES By the end of this section, you will be able to: Figure 2.36 Problem-solving skills are essential to your success in Physics. (credit: scui3asteveo, Flickr) Problem-solving skills are obviously essential to success in a quantitative course in physics. More importantly,…
LEARNING OBJECTIVES By the end of this section, you will be able to: Figure 2.24 Kinematic equations can help us describe and predict the motion of moving objects such as these kayaks racing in Newbury, England. (credit: Barry Skeates, Flickr) We might…
LEARNING OBJECTIVES By the end of this section, you will be able to: Figure 2.12 A plane decelerates, or slows down, as it comes in for landing in St. Maarten. Its acceleration is opposite in direction to its velocity. (credit: Steve Conry,…
