physics formulas

UNIT 1 speed and velocity -- m/s acceleration -- m/s^2 time -- seconds distance -- meter mass -- kg force -- Newtons (N) weight (is a force) -- Newtons (N) gravitational field strength -- (N/kg) 9.8 or 10

average speed, distance moved, time taken

v = s / t

average speed, v = distance moved, s / time taken, t

acceleration, change in velocity, time taken

a = ( v - u ) / t

acceleration, a = change in velocity, (v - u) / time taken, t

final speed, initial speed, acceleration, distance moved

v² = u² + (2 * a * s)

(final speed)² = (initial speed)² + (2 * acceleration * distance moved)

area under velocity-time graph = distance traveled

distance traveled = ½ * base * height

force, mass, acceleration

f = m * a

force = mass * acceleration

weight, mass, gravitational field strength

W = m * g

weight = mass * gravitational field strength
