science formula for 9

To find....	....use this formula
Speed	where v is speed in metres per second, s is distance in metres, and t is time in seconds
Velocity	where v is velocity in metres per second, d is displacement in metres, and t is time in seconds
Acceleration	where a is acceleration in m/s2, v is change in velocity in metres per second, and t is time in seconds
Weight	W = mg where W is weight, m is mass in kilograms and g is acceleration due to gravity in m/s2 (on Earth, acceleration due to gravity is approximately 9.8 m/s2)
Force	F = ma where F is force in newtons, m is mass in kilograms, and a is acceleration in m/s2
Work Done	W = Fs where W is work in joules, F is force in newtons, and s is the distance over which the force is applied
Gravitational Potential Energy	GPE = mgh where GPE is gravitational potential energy in joules, m is mass in kilograms, g is the acceleration due to gravity in m/s2, and h is height in metres (on Earth, acceleration due to gravity is approximately 9.8 m/s2)
Elastic Potential Energy	EPE =  kx2 where EPE is elastic potential energy in joules, k is the spring constant of the object, and x is the length of extension or compression in metres
Power	P = W t where P is power in watts, W is work in joules, and t is time in seconds
Mechanical Advantage	where MA is the mechanical advantage and the load and effort are measured in newtons or where both distances are measured in metres in a first or second class lever
