M1-Kinematics of a particle moving in a straight line

HideShow resource information

Important symbols

S-Distance/displacement (m)

U-Initial velocity (ms^-1)

V-Final velocity (ms^-1)

A-Acceleration (ms^-2)

T-Time (s)

1 of 4

5 formulae to remember

v=u+at

s=(u+v)/2 xt

v^2=u^2+2as

s=ut+1/2at^2

s=vt-1/2at^2

Acceleration

-If a particle is slowing it has a negative acceleration-deceleration/retardation.

-A model free falling vertically in a straight line has a downward acceleration of g=9.8ms^-2. Upwards is g=-9.8ms^-2

Graphs

-Gradient of a speed-time graph=acceleration of a particle

-Area under speed-time graph=distance moved by the particle

-Area of a Trapezium=1/2(a+b)h

-At constant speed, distance=speed x time
