The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page demonstrates the process with 20 sample problems and accompanying solutions.

Δt or t : change in time or time (s) Δv : change in velocity (m/s) v i: initial velocity (m/s) v f: final velocity (m/s) a : acceleration (m/s2) (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)
know formulae for constant velocity and constant acceleration. be able to solve problems on motion with constant velocity and constant acceleration, including problems involving several such stages. understand what is meant by the terms ‘average speed’ and ‘average velocity’. 1.1 Motion with constant velocity. y of 100 paces per minute due east. Wh
d1 and d2 represent two different distances that object one or two are from the fulcrum or rotational point. d : distance between objects (m) m2 : mass two. π : pie (3.14 rounded) G : universal gravitation constant. Fg : Force of Gravity (N)
The gradient of the displacement–time graph is the velocity of the object. Mathematically this is the equivalent of dividing the y-axis quantity by the x-axis quantity: in this case displacement divided by time. Displacement divided by time is rate of change of displacement, which is velocity.
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.
