An example of a kinematics problem is to determine the final velocity of a ball that has been dropped from a certain height to the ground, according to The Physics Classroom. Kinematics problems generally concern the motion of objects and are often solvable using a set of four equations. A typical kinematics problem can involve an object in free-fall, the projectile on a parabolic arc or the motion of a vehicle.
The quantities associated to the motion of objects include velocity, time, displacement and acceleration. There are many simple illustrative examples problems that make use of these variables to describe the motion of objects, such as motor vehicles. An example of such a problem is to determine the time it would take in hours for a vehicle to travel a certain number of miles when the velocity of the vehicle in miles per hour is given. Another formulation of a kinematics problem involving the motion of vehicles is to determine the velocity of a car in miles per hour when the distance in miles and the travel time is known. Kinematics problems often require solvers to convert from one unit of measurement to another, such as from seconds to hours.
