Density
density = mass / volume
1 of 23
Distance
distance = speed x time
2 of 23
Speed
speed = distance / time
3 of 23
Acceleration
acceleration= change in velocity / time
4 of 23
Kinetic Energy
kinetic energy = 0.5 x mass x velocity²
5 of 23
Force
force = mass x acceleration
6 of 23
Momentum
momentum = mass x velocity
7 of 23
Work Done
work done = force x distance
8 of 23
Power (with work done & time)
power = work done / time
9 of 23
Power (with energy & time)
power = energy / time
10 of 23
Force Exerted by Spring
force exerted by spring = spring constant x extension
11 of 23
Weight
weight = mass x gravitational field strength
12 of 23
Gravitational Potential Energy
gravitational potential energy = mass x gravitational field strength x height
13 of 23
Pressure
pressure = force applied to surface / area of surface
14 of 23
Moment
moment = force x distance (in the direction of the force)
15 of 23
Charge
charge = current x time
16 of 23
Potential Difference
potential difference = current x resistance
17 of 23
Energy Transferred (with charge & potential difference)
energy transferred = charge x potential difference
18 of 23
Power (with potential difference & current)
power = potential difference x current
19 of 23
Power (with current & resistance)
power = current² x resistance
20 of 23
Energy Transferred (with power & time)
energy transferred = power x time
