Equilibrium in 1D What is Newton’s First Law of Motion (N1L)? An object at rest will stay at rest, and an object moving with constant velocity will continue to move with constant velocity, unless a...
Force Diagrams Why do we need force diagrams? Force diagrams are used to help understand a given scenario and show which forces are acting on which particles and in which direction they are acting ...
Acceleration due to Gravity What is acceleration due to gravity? If motion is vertical and no other forces are acting on a particle, the acceleration of the particle will be due to gravity Accelera...
suvat in 1D What are the suvat (constant acceleration) formulae? For constant acceleration there are five suvat formula: How do I identify values for suvat within a question? Common phrases for di...
Deriving the suvat Formulae What is suvat? suvat is an acronym for the five quantities used when modelling motion in a straight-line with constant acceleration s – displacement (from the starting p...
Using Calculus in 1D How is calculus used in kinematics? s, v and a are all functions of time Velocity, v, is the rate of change of displacement, s, with respect to time Acceleration, a, is the rat...
Drawing Travel Graphs How do I draw a displacement-time graph or a velocity-time graph? You may be asked to draw a displacement-time graph or a velocity-time graph You will be given information abo...
Velocity-Time Graphs What is a velocity-time graph? Velocity- time graphs show the velocity of an object as it moves in a straight line They show velocity (on the vertical axis) against time (on th...
Displacement-Time Graphs What is a displacement-time graph? Displacement-time graphs show the displacement of an object from a fixed origin as it moves in a straight line They show displacement (on...
