Question | Answer |
---|---|
V^2 (Final velocity^2) Without the T | U^2 + 2AS (Initial velocity^2 + 2 x Acceleration x Displacement) |
V (Final velocity) Without the S | U +AT (Initial velocity + Acceleration x Total time) |
S (Displacment) Without the A | (U + V / 2)T ((Initial velocity + Final velocity/2) x Total time |
S (Displacement) Without the V | (UT) + (1/2 AT^2) (Initial velocity x Total time) + (1/2 Acceleration x Total time^2) |
S (Displacement) Without the U | (VT) - (1/2AT^2) (FInal velocity x Total time) - (1/2 Acceleration x Total time^2) |
Force | Mass x Acceleration |
Definition of velocity | Rate of change of acceleration |
Definition of velocity (symbol) | v = change in s / change in t |
Definition of acceleration | rate of change of velocity |
Definition of acceleration (symbol) | a = change in v / change in t |
momentum | Mass x Velocity p = mv |
Impulse definition | Change in momentum in a time interval |
Impulse equation | F x change in t = change in (m x v) |
Equation relating force momentum and time | F = change in (m x v) / t |
Work done with force and distance | w = fs w = f x s x cos(theta) |
Kinetic energy | 1/2 x m x v^2 |
Force with power and velocity | F = p / v |
