After completeing this chapter, the reader will be able to:
| angle of projection | the direction at which a body is projected with respect to the horizontal |
| apex | the highest point in the trajectory of a projectile |
| average | occurring over a designated time interval |
| initial velocity | vector quantity incorporating both angle and speed of projection |
| instantaneous | occurring during a small interval of time |
| kinematics | the form, pattern, or sequencing of movement with respect to time |
| laws of constant acceleration | three formulas relating displacement, velocity, acceleration, and time when acceleration is unchanging |
| linear acceleration | the rate of change in linear velocity |
| linear displacement | change in location, or the directed distance from initial to final location |
| linear velocity | the rate of change in location |
| meter | most common international unit of length on which the metric system is based |
| projectile | a body in free fall that is subject only to the forces of gravity and air resistance |
| projection speed | the magnitude of projection velocity |
| range | the horizontal displacement of a projectile at landing |
| relative projection height | the difference between projection height and landing height |
| trajectory | the flight path of a projectile |
