Projectile motion problems

Parabolic water trajectory Components of initial velocity of parabolic throwing Projectile motion is a form of motion experienced by an object or particle a projectile that is thrown near the Earth's surface and moves along a curved path under the action of gravity only in particular, the effects of air resistance are assumed to be negligible. This curved path was shown by Galileo to be a parabola. The study of such motions is called ballisticsand such a trajectory is a ballistic trajectory. The solution of the problem now requires the selection of an appropriate strategy for using the kinematic equations and the known information to solve for the unknown quantities. It will almost always be the case that such a strategy demands that one of the vertical equations be used to determine the time of flight of the projectile and then one of the horizontal equations be used to find the other unknown quantities or vice versa - first use the horizontal and then the vertical equation.

An organized listing of known quantities as in the table above provides cues for the selection of the strategy. For example, the table above reveals that there Projectile motion problems three quantities known about the vertical motion of the pool ball. Since each equation has four variables in it, knowledge of three of the variables allows one to calculate a fourth variable.

Thus, it would be reasonable that a vertical equation is used with the vertical values to determine time and then the horizontal equations be used to determine the horizontal displacement x. Once the appropriate equation has been selected, the physics problem becomes transformed into an algebra problem.

By substitution of known values, the equation takes the form of The following procedure summarizes the above problem-solving approach. Carefully read the problem and list known and unknown information in terms of the symbols of the kinematic equations.

For convenience sake, make a table with horizontal information on one side and vertical information on the other side. Identify the unknown quantity that the problem requests you to solve for. Select either a horizontal or vertical equation to solve for the time of flight of the projectile.

With the time determined, use one of the other equations to solve for the unknown. Usually, if a horizontal equation is used to solve for time, then a vertical equation can be used to solve for the final unknown quantity. One caution is in order.

The sole reliance upon 4- and 5-step procedures to solve physics problems is always a dangerous approach. Physics problems are usually just that - problems! While problems can often be simplified by the use of short procedures as the one above, not all problems can be solved with the above procedure.

Problem solving is not like cooking; it is not a mere matter of following a recipe. Rather, problem solving requires careful reading, a firm grasp of conceptual physics, critical thought and analysis, and lots of disciplined practice. Never divorce conceptual understanding and critical thinking from your approach to solving problems.

Projectile Motion Problems Explained A projectile is fired into the air from the edge of a m high cliff at an angle of deg above the horizontal. The projectile hits a . PROJECTILE MOTION We see one dimensional motion in previous topics. Now, we will try to explain motion in two dimensions that is exactly called “projectile motion”.

In this type of motion gravity is the only factor acting on our objects. We can have different types of projectile type.

For example, you throw the ball straight upward, or you kick a ball .

On this page I put together a collection of projectile motion problems to help you understand projectile motion better. The required equations and background reading to solve these problems is given on the projectile motion page. I also provide hints and numerical answers for these problems.

Projectile motion is a form of motion experienced by an object or particle (a projectile) that is thrown near the Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible). The two sets of three equations above are the kinematic equations that will be used to solve projectile motion problems.

Solving Projectile Problems To illustrate the usefulness of the above equations in making predictions about the motion of a projectile, consider the solution to the following problem.
