Physics Equations

Exponential

y∝x²

curve sloping upwards

inverse

y∝1/x

curving sloping downwards

fractional

y∝√x

looks like a hunch back

inverse flipped

inverse squared

y∝1/x²

like an inverse but closer to axises

velocity

v=d/t

acceleration

a=v/t

• v is also change in velocity so vf-vi if applicable (if there are two velocities)

area of a triangle

A=1/2 bh

used to find displacement

area of a rectangle

A= L x W

How to find range (horizontal distance traveled)

dx=vxt (variation of velocity equation)

net force

Fnet=ma

ref table: a=fnet/m

• if you have an acceleration you have a net force and vice versa (constant velocity = no acceleration = no net force)

• forces cause objects to accelerate

gravitational force

Fg=mg

• in reference table as g=Fg/m

• mass is different than weight (kg v Newtons)
