Physics to Memorise (NOT ON REF SHEET)

Object moving down and inclined frictionless surface

Object at rest on an incline

Object accelerating down a rough incline

Projectile range shortcut

Work and energy of a system

Must account for each objects energy (sum up the masses) velocity of a system is always same

Ideally banked curves

Critical speed on a rotating plate

Critical speed loops and hills

For any point inside the mass

graph the acceleration due to gravity the farther u get from earth

Inside earth, acceleration increases linearly till reaches 9.8, then decreases with root curve the farther u get

Escape velocity

Velocity on different parts of a rolling object

Hole in the tank

Venturi Effect

High velocity means low pressure

Revolutions to radians to degrees

1revolution = 2pi rad = 360 degree

Keplers Law

Unit for density

Kg/m³

Unit for momentum

Kgm/s
