Term | Definition |
---|---|
= d / t | v |
= d/v | t |
= txv | d |
= ma | F |
= mg | F |
=mgh | Ep |
=v/t | a |
=axt | v |
=a/v | t |
=F/A | P |
=1/2 mx v2 | Ek |
=E/t | P |
g on earth | 10 N/lg |
W | = Fxd |
distance (m) = velocity (m/s) x time (s) | d = v x t |
time = distance / velocity | t = d / v |
velocity = distance / time | v= d / t |
force = mass x acceleration | F = m a |
force (weight) = mass x gravity | F = m g |
gravitational potential energy (J) = mass (kg) x gravity (N/kg) x height (m) | Ep = mgh |
acceleration = velocity / time | a = v/t |
velocity = acceleration x time | v = at |
time (s) = acceleration (m/s2 squared) / velocity (m/s) | t = a/v |
Pressure (Pa) = Force (N)/ Area (m2) squared | P = F/A |
Kinetic energy (J) = 1/2( mass (kg)) x (velocity (m/s))2 (squared) | Ek = 1/2mv2 (squared) |
Power (W) = Energy (J) / time (s) | P = E/t |
Work (J) = Force (N) x distance (m) | W = Fd |
convert m/s to km/hr x 3.6 | convert km/hr to m/s divide by 3.6 |
