(note: on many different equation sheets x is substituted by d for displacement) Variables (mks unit) Δy or y : change in position or displacement (m) in the y axis Δv : change in velocity (m/s) iy: initial Y axis velocity (m/s) V fy: final Y axis velocity (m/s) g : acceleration due to gravity (m/s )

In this chapter, we study speed, velocity, and acceleration for motion in one-dimension. One dimensional motion is motion along a straight line, like the motion of a glider on an airtrack.

In physics, the motion is the change in position of an object with respect to its surroundings in a given interval of time. The motion of an object with some mass can be described in terms of the following: Distance. Displacement. Speed. Velocity. Time. Acceleration. Main types of motion. Translatory motion (linear motion) . Rotatory motion.
When object starts from rest and undergoes constant acceleration: Position is proportional to the square of time. Position changes result in the sequence of odd numbers. Falling bodies exhibit this type of motion (since g is constant).

Newton's Laws: Forces and Motion. A force is a push or a pull. A force is a vector : it has a magnitude and a direction. Forces add like vectors, not like scalars. Example: Two forces, labeled. same magnitude. F1 and F2, are both acting on the same object. The forces have the.
