Projectiles

There are two things you have to remember in working projectile problems. The first lets you get started on the problem and the second often helps you when you get stuck.

First: The motion in any projectile problem is analyzed in two perpendicular directions, one oriented in the direction of the acceleration and the other (direction) perpendicular to the first.

Second: Projectile motion is parabolic. The symmetry of parabolas will help you in analyzing problems.

In the two books How to Solve Physics Problems and Calculus for the Utterly Confused parabolas are studied sufficient for you to become very familiar with the symmetry properties of parabolas and their application to projectile problems. If you have trouble applying the symmetry properties of parabolas to projectile problems consult either of these books.

The equations for these problems are the kinematic equations of motion used in the previous two sections. Remember, the coordinate systems are arranged so the acceleration is a constant non-zero value in one direction and zero in the other direction.

Our experience is that if the acceleration, velocity and position equations are written for each direction it is difficult to get the problem wrong. Sometimes the procedure adds a little extra work but it will result in higher test grades and make your working of the problems easier.

Projectile problems are listed below. After viewing each problem return to this page to select another problem.

Projectile problems are discussed in greater detail in our books How to Solve Physics Problems and Physics for the Utterly Confused. Click on these links to go to a review and some sample pages. These books can be purchased at the online bookstores linked in the reviews.
