In this section, we consider two-dimensional projectile motion, and our treatment neglects the effects of air resistance.

The motion of falling objects as discussed in Motion Along a Straight Line is a simple one-dimensional type of projectile motion in which there is no horizontal movement. Such objects are called projectiles and their path is called a trajectory. Some examples include meteors as they enter Earth’s atmosphere, fireworks, and the motion of any ball in sports. The applications of projectile motion in physics and engineering are numerous. Projectile motion is the motion of an object thrown or projected into the air, subject only to acceleration as a result of gravity. Calculate the trajectory of a projectile.Find the time of flight and impact velocity of a projectile that lands at a different height from that of launch.

Calculate the range, time of flight, and maximum height of a projectile that is launched and impacts a flat, horizontal surface.Use one-dimensional motion in perpendicular directions to analyze projectile motion.2.2 Coordinate Systems and Components of a Vectorģ.1 Position, Displacement, and Average Velocityģ.3 Average and Instantaneous Accelerationģ.6 Finding Velocity and Displacement from AccelerationĤ.5 Relative Motion in One and Two DimensionsĨ Potential Energy and Conservation of EnergyĨ.2 Conservative and Non-Conservative ForcesĨ.4 Potential Energy Diagrams and Stabilityġ0.2 Rotation with Constant Angular Accelerationġ0.3 Relating Angular and Translational Quantitiesġ0.4 Moment of Inertia and Rotational Kinetic Energyġ0.8 Work and Power for Rotational Motionġ3.1 Newton’s Law of Universal Gravitationġ3.3 Gravitational Potential Energy and Total Energyġ5.3 Comparing Simple Harmonic Motion and Circular Motionġ7.4 Normal Modes of a Standing Sound Waveīy the end of this section, you will be able to:
